Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720174, here are decompositions:

  • 3 + 8720171 = 8720174
  • 13 + 8720161 = 8720174
  • 37 + 8720137 = 8720174
  • 61 + 8720113 = 8720174
  • 103 + 8720071 = 8720174
  • 223 + 8719951 = 8720174
  • 271 + 8719903 = 8720174
  • 373 + 8719801 = 8720174

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 8,720,174 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 8720174 first appears in π at position 124,592 of the decimal expansion (the 124,592ordinal-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.
