Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136438, here are decompositions:

  • 17 + 136421 = 136438
  • 41 + 136397 = 136438
  • 59 + 136379 = 136438
  • 101 + 136337 = 136438
  • 191 + 136247 = 136438
  • 461 + 135977 = 136438
  • 509 + 135929 = 136438
  • 587 + 135851 = 136438

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 136,438 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 136438 first appears in π at position 112,250 of the decimal expansion (the 112,250ordinal-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.
