Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939408, here are decompositions:

  • 17 + 939391 = 939408
  • 31 + 939377 = 939408
  • 47 + 939361 = 939408
  • 59 + 939349 = 939408
  • 61 + 939347 = 939408
  • 109 + 939299 = 939408
  • 179 + 939229 = 939408
  • 227 + 939181 = 939408

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 939,408 and was likely granted around 1909.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 939408 first appears in π at position 246,557 of the decimal expansion (the 246,557ordinal-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.
