Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634620, here are decompositions:

  • 3 + 8634617 = 8634620
  • 103 + 8634517 = 8634620
  • 139 + 8634481 = 8634620
  • 151 + 8634469 = 8634620
  • 193 + 8634427 = 8634620
  • 199 + 8634421 = 8634620
  • 223 + 8634397 = 8634620
  • 229 + 8634391 = 8634620

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 8,634,620 and was likely granted around 2014.

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

Position in π

The digit sequence 8634620 first appears in π at position 239,851 of the decimal expansion (the 239,851ordinal-suffix:st 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.
