Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627786, here are decompositions:

  • 73 + 8627713 = 8627786
  • 283 + 8627503 = 8627786
  • 313 + 8627473 = 8627786
  • 457 + 8627329 = 8627786
  • 487 + 8627299 = 8627786
  • 613 + 8627173 = 8627786
  • 619 + 8627167 = 8627786
  • 757 + 8627029 = 8627786

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 8,627,786 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 8627786 first appears in π at position 467,586 of the decimal expansion (the 467,586ordinal-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.
