Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631560, here are decompositions:

  • 43 + 8631517 = 8631560
  • 61 + 8631499 = 8631560
  • 109 + 8631451 = 8631560
  • 181 + 8631379 = 8631560
  • 193 + 8631367 = 8631560
  • 229 + 8631331 = 8631560
  • 241 + 8631319 = 8631560
  • 277 + 8631283 = 8631560

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 8,631,560 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 8631560 first appears in π at position 454,924 of the decimal expansion (the 454,924ordinal-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.
