Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700240, here are decompositions:

  • 47 + 8700193 = 8700240
  • 71 + 8700169 = 8700240
  • 79 + 8700161 = 8700240
  • 127 + 8700113 = 8700240
  • 181 + 8700059 = 8700240
  • 193 + 8700047 = 8700240
  • 229 + 8700011 = 8700240
  • 233 + 8700007 = 8700240

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 8,700,240 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 8700240 first appears in π at position 626,588 of the decimal expansion (the 626,588ordinal-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.
