Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138302, here are decompositions:

  • 13 + 138289 = 138302
  • 19 + 138283 = 138302
  • 61 + 138241 = 138302
  • 139 + 138163 = 138302
  • 163 + 138139 = 138302
  • 223 + 138079 = 138302
  • 433 + 137869 = 138302
  • 499 + 137803 = 138302

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 138,302 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 138302 first appears in π at position 924,674 of the decimal expansion (the 924,674ordinal-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.
