Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662866, here are decompositions:

  • 7 + 8662859 = 8662866
  • 13 + 8662853 = 8662866
  • 59 + 8662807 = 8662866
  • 67 + 8662799 = 8662866
  • 83 + 8662783 = 8662866
  • 97 + 8662769 = 8662866
  • 137 + 8662729 = 8662866
  • 269 + 8662597 = 8662866

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 8,662,866 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 8662866 first appears in π at position 62,232 of the decimal expansion (the 62,232ordinal-suffix:nd 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.
