Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938220, here are decompositions:

  • 13 + 938207 = 938220
  • 37 + 938183 = 938220
  • 103 + 938117 = 938220
  • 113 + 938107 = 938220
  • 131 + 938089 = 938220
  • 137 + 938083 = 938220
  • 149 + 938071 = 938220
  • 163 + 938057 = 938220

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 938,220 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 938220 first appears in π at position 663,352 of the decimal expansion (the 663,352ordinal-suffix:nd 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.
