Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660008, here are decompositions:

  • 11 + 8659997 = 8660008
  • 59 + 8659949 = 8660008
  • 197 + 8659811 = 8660008
  • 239 + 8659769 = 8660008
  • 317 + 8659691 = 8660008
  • 419 + 8659589 = 8660008
  • 449 + 8659559 = 8660008
  • 719 + 8659289 = 8660008

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 8,660,008 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 8660008 first appears in π at position 271,538 of the decimal expansion (the 271,538ordinal-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.
