Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707972, here are decompositions:

  • 3 + 8707969 = 8707972
  • 89 + 8707883 = 8707972
  • 131 + 8707841 = 8707972
  • 179 + 8707793 = 8707972
  • 191 + 8707781 = 8707972
  • 311 + 8707661 = 8707972
  • 593 + 8707379 = 8707972
  • 683 + 8707289 = 8707972

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 8,707,972 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 8707972 first appears in π at position 901,112 of the decimal expansion (the 901,112ordinal-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.
