Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938628, here are decompositions:

  • 11 + 938617 = 938628
  • 17 + 938611 = 938628
  • 37 + 938591 = 938628
  • 59 + 938569 = 938628
  • 137 + 938491 = 938628
  • 181 + 938447 = 938628
  • 191 + 938437 = 938628
  • 241 + 938387 = 938628

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 938,628 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 938628 first appears in π at position 150,106 of the decimal expansion (the 150,106ordinal-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.
