Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938420, here are decompositions:

  • 61 + 938359 = 938420
  • 73 + 938347 = 938420
  • 79 + 938341 = 938420
  • 97 + 938323 = 938420
  • 127 + 938293 = 938420
  • 157 + 938263 = 938420
  • 163 + 938257 = 938420
  • 313 + 938107 = 938420

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 938,420 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 938420 first appears in π at position 741,537 of the decimal expansion (the 741,537ordinal-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.
