Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131462, here are decompositions:

  • 13 + 131449 = 131462
  • 31 + 131431 = 131462
  • 151 + 131311 = 131462
  • 211 + 131251 = 131462
  • 241 + 131221 = 131462
  • 313 + 131149 = 131462
  • 349 + 131113 = 131462
  • 421 + 131041 = 131462

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 131,462 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 131462 first appears in π at position 12,915 of the decimal expansion (the 12,915ordinal-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.
