Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500842, here are decompositions:

  • 3 + 500839 = 500842
  • 11 + 500831 = 500842
  • 101 + 500741 = 500842
  • 113 + 500729 = 500842
  • 149 + 500693 = 500842
  • 239 + 500603 = 500842
  • 263 + 500579 = 500842
  • 359 + 500483 = 500842

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 500,842 and was likely granted around 1893.

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

Position in π

The digit sequence 500842 first appears in π at position 203,476 of the decimal expansion (the 203,476ordinal-suffix:th 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.
