Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679980, here are decompositions:

  • 7 + 8679973 = 8679980
  • 37 + 8679943 = 8679980
  • 97 + 8679883 = 8679980
  • 109 + 8679871 = 8679980
  • 139 + 8679841 = 8679980
  • 241 + 8679739 = 8679980
  • 271 + 8679709 = 8679980
  • 373 + 8679607 = 8679980

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 8,679,980 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 8679980 first appears in π at position 941,040 of the decimal expansion (the 941,040ordinal-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.
