Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131204, here are decompositions:

  • 61 + 131143 = 131204
  • 103 + 131101 = 131204
  • 163 + 131041 = 131204
  • 181 + 131023 = 131204
  • 193 + 131011 = 131204
  • 223 + 130981 = 131204
  • 277 + 130927 = 131204
  • 331 + 130873 = 131204

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 131,204 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 131204 first appears in π at position 430,584 of the decimal expansion (the 430,584ordinal-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.
