Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743866, here are decompositions:

  • 13 + 8743853 = 8743866
  • 23 + 8743843 = 8743866
  • 29 + 8743837 = 8743866
  • 59 + 8743807 = 8743866
  • 97 + 8743769 = 8743866
  • 113 + 8743753 = 8743866
  • 149 + 8743717 = 8743866
  • 193 + 8743673 = 8743866

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 8,743,866 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 8743866 first appears in π at position 511,748 of the decimal expansion (the 511,748ordinal-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.
