Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938724, here are decompositions:

  • 11 + 938713 = 938724
  • 43 + 938681 = 938724
  • 47 + 938677 = 938724
  • 107 + 938617 = 938724
  • 113 + 938611 = 938724
  • 151 + 938573 = 938724
  • 191 + 938533 = 938724
  • 233 + 938491 = 938724

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 938,724 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 938724 first appears in π at position 13,424 of the decimal expansion (the 13,424ordinal-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.
