Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938920, here are decompositions:

  • 41 + 938879 = 938920
  • 89 + 938831 = 938920
  • 113 + 938807 = 938920
  • 173 + 938747 = 938920
  • 239 + 938681 = 938920
  • 347 + 938573 = 938920
  • 383 + 938537 = 938920
  • 461 + 938459 = 938920

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 938,920 and was likely granted around 1909.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
