Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729256, here are decompositions:

  • 7 + 8729249 = 8729256
  • 13 + 8729243 = 8729256
  • 17 + 8729239 = 8729256
  • 37 + 8729219 = 8729256
  • 73 + 8729183 = 8729256
  • 83 + 8729173 = 8729256
  • 139 + 8729117 = 8729256
  • 149 + 8729107 = 8729256

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 8,729,256 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 8729256 first appears in π at position 247,764 of the decimal expansion (the 247,764ordinal-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.
