Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747788, here are decompositions:

  • 11 + 8747777 = 8747788
  • 29 + 8747759 = 8747788
  • 41 + 8747747 = 8747788
  • 227 + 8747561 = 8747788
  • 317 + 8747471 = 8747788
  • 347 + 8747441 = 8747788
  • 461 + 8747327 = 8747788
  • 617 + 8747171 = 8747788

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 8,747,788 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 8747788 first appears in π at position 105,449 of the decimal expansion (the 105,449ordinal-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.
