Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627998, here are decompositions:

  • 11 + 8627987 = 8627998
  • 59 + 8627939 = 8627998
  • 89 + 8627909 = 8627998
  • 101 + 8627897 = 8627998
  • 131 + 8627867 = 8627998
  • 191 + 8627807 = 8627998
  • 257 + 8627741 = 8627998
  • 317 + 8627681 = 8627998

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 8,627,998 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 8627998 first appears in π at position 374,237 of the decimal expansion (the 374,237ordinal-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.
