Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688630, here are decompositions:

  • 17 + 8688613 = 8688630
  • 19 + 8688611 = 8688630
  • 23 + 8688607 = 8688630
  • 29 + 8688601 = 8688630
  • 37 + 8688593 = 8688630
  • 47 + 8688583 = 8688630
  • 53 + 8688577 = 8688630
  • 59 + 8688571 = 8688630

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 8,688,630 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 8688630 first appears in π at position 610,855 of the decimal expansion (the 610,855ordinal-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.
