Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717866, here are decompositions:

  • 5 + 8717861 = 8717866
  • 23 + 8717843 = 8717866
  • 83 + 8717783 = 8717866
  • 149 + 8717717 = 8717866
  • 233 + 8717633 = 8717866
  • 593 + 8717273 = 8717866
  • 653 + 8717213 = 8717866
  • 743 + 8717123 = 8717866

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 8,717,866 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 8717866 first appears in π at position 308,446 of the decimal expansion (the 308,446ordinal-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.
