Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131048, here are decompositions:

  • 7 + 131041 = 131048
  • 37 + 131011 = 131048
  • 61 + 130987 = 131048
  • 67 + 130981 = 131048
  • 79 + 130969 = 131048
  • 241 + 130807 = 131048
  • 349 + 130699 = 131048
  • 367 + 130681 = 131048

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 131,048 and was likely granted around 1872.

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

Position in π

The digit sequence 131048 first appears in π at position 557,233 of the decimal expansion (the 557,233ordinal-suffix:rd 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.
