Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138350, here are decompositions:

  • 13 + 138337 = 138350
  • 31 + 138319 = 138350
  • 61 + 138289 = 138350
  • 67 + 138283 = 138350
  • 103 + 138247 = 138350
  • 109 + 138241 = 138350
  • 193 + 138157 = 138350
  • 211 + 138139 = 138350

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 138,350 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 138350 first appears in π at position 5,699 of the decimal expansion (the 5,699ordinal-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.
