Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617680, here are decompositions:

  • 53 + 8617627 = 8617680
  • 131 + 8617549 = 8617680
  • 157 + 8617523 = 8617680
  • 167 + 8617513 = 8617680
  • 233 + 8617447 = 8617680
  • 241 + 8617439 = 8617680
  • 263 + 8617417 = 8617680
  • 283 + 8617397 = 8617680

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 8,617,680 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8617680 first appears in π at position 738,751 of the decimal expansion (the 738,751ordinal-suffix:st 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.
