Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627788, here are decompositions:

  • 11 + 8627777 = 8627788
  • 47 + 8627741 = 8627788
  • 89 + 8627699 = 8627788
  • 107 + 8627681 = 8627788
  • 149 + 8627639 = 8627788
  • 179 + 8627609 = 8627788
  • 227 + 8627561 = 8627788
  • 347 + 8627441 = 8627788

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 8,627,788 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 8627788 first appears in π at position 780,656 of the decimal expansion (the 780,656ordinal-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.
