Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131876, here are decompositions:

  • 37 + 131839 = 131876
  • 79 + 131797 = 131876
  • 97 + 131779 = 131876
  • 127 + 131749 = 131876
  • 163 + 131713 = 131876
  • 379 + 131497 = 131876
  • 397 + 131479 = 131876
  • 439 + 131437 = 131876

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 131,876 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 131876 first appears in π at position 261,447 of the decimal expansion (the 261,447ordinal-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.
