Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723946, here are decompositions:

  • 13 + 8723933 = 8723946
  • 17 + 8723929 = 8723946
  • 37 + 8723909 = 8723946
  • 43 + 8723903 = 8723946
  • 47 + 8723899 = 8723946
  • 53 + 8723893 = 8723946
  • 59 + 8723887 = 8723946
  • 67 + 8723879 = 8723946

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 8,723,946 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 8723946 first appears in π at position 711,018 of the decimal expansion (the 711,018ordinal-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.
