Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625886, here are decompositions:

  • 53 + 8625833 = 8625886
  • 179 + 8625707 = 8625886
  • 197 + 8625689 = 8625886
  • 359 + 8625527 = 8625886
  • 419 + 8625467 = 8625886
  • 569 + 8625317 = 8625886
  • 653 + 8625233 = 8625886
  • 683 + 8625203 = 8625886

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 8,625,886 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 8625886 first appears in π at position 524,124 of the decimal expansion (the 524,124ordinal-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.
