Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652780, here are decompositions:

  • 7 + 8652773 = 8652780
  • 13 + 8652767 = 8652780
  • 83 + 8652697 = 8652780
  • 139 + 8652641 = 8652780
  • 151 + 8652629 = 8652780
  • 167 + 8652613 = 8652780
  • 179 + 8652601 = 8652780
  • 193 + 8652587 = 8652780

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 8,652,780 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 8652780 first appears in π at position 48,697 of the decimal expansion (the 48,697ordinal-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.
