Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640274, here are decompositions:

  • 11 + 8640263 = 8640274
  • 23 + 8640251 = 8640274
  • 53 + 8640221 = 8640274
  • 113 + 8640161 = 8640274
  • 257 + 8640017 = 8640274
  • 353 + 8639921 = 8640274
  • 521 + 8639753 = 8640274
  • 563 + 8639711 = 8640274

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 8,640,274 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 8640274 first appears in π at position 960,218 of the decimal expansion (the 960,218ordinal-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.
