Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136442, here are decompositions:

  • 13 + 136429 = 136442
  • 43 + 136399 = 136442
  • 109 + 136333 = 136442
  • 139 + 136303 = 136442
  • 181 + 136261 = 136442
  • 331 + 136111 = 136442
  • 349 + 136093 = 136442
  • 373 + 136069 = 136442

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 136,442 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 136442 first appears in π at position 441,371 of the decimal expansion (the 441,371ordinal-suffix:st 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.
