Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938380, here are decompositions:

  • 11 + 938369 = 938380
  • 29 + 938351 = 938380
  • 71 + 938309 = 938380
  • 101 + 938279 = 938380
  • 137 + 938243 = 938380
  • 173 + 938207 = 938380
  • 197 + 938183 = 938380
  • 251 + 938129 = 938380

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 938,380 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 938380 first appears in π at position 759,688 of the decimal expansion (the 759,688ordinal-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.
