Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624842, here are decompositions:

  • 71 + 8624771 = 8624842
  • 89 + 8624753 = 8624842
  • 173 + 8624669 = 8624842
  • 269 + 8624573 = 8624842
  • 383 + 8624459 = 8624842
  • 449 + 8624393 = 8624842
  • 593 + 8624249 = 8624842
  • 599 + 8624243 = 8624842

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,624,842 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8624842 first appears in π at position 100,672 of the decimal expansion (the 100,672ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
