Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102972, here are decompositions:

  • 5 + 102967 = 102972
  • 19 + 102953 = 102972
  • 41 + 102931 = 102972
  • 43 + 102929 = 102972
  • 59 + 102913 = 102972
  • 61 + 102911 = 102972
  • 101 + 102871 = 102972
  • 113 + 102859 = 102972

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 102,972 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 102972 first appears in π at position 541,262 of the decimal expansion (the 541,262ordinal-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.
