Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138326, here are decompositions:

  • 3 + 138323 = 138326
  • 7 + 138319 = 138326
  • 37 + 138289 = 138326
  • 43 + 138283 = 138326
  • 79 + 138247 = 138326
  • 163 + 138163 = 138326
  • 379 + 137947 = 138326
  • 457 + 137869 = 138326

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 138,326 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 138326 first appears in π at position 174,049 of the decimal expansion (the 174,049ordinal-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.
