Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938520, here are decompositions:

  • 13 + 938507 = 938520
  • 29 + 938491 = 938520
  • 61 + 938459 = 938520
  • 67 + 938453 = 938520
  • 73 + 938447 = 938520
  • 83 + 938437 = 938520
  • 127 + 938393 = 938520
  • 151 + 938369 = 938520

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 938,520 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 938520 first appears in π at position 297,202 of the decimal expansion (the 297,202ordinal-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.
