Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660940, here are decompositions:

  • 7 + 8660933 = 8660940
  • 11 + 8660929 = 8660940
  • 19 + 8660921 = 8660940
  • 31 + 8660909 = 8660940
  • 53 + 8660887 = 8660940
  • 173 + 8660767 = 8660940
  • 193 + 8660747 = 8660940
  • 199 + 8660741 = 8660940

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 8,660,940 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 8660940 first appears in π at position 375,833 of the decimal expansion (the 375,833ordinal-suffix:rd 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.
