Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938406, here are decompositions:

  • 13 + 938393 = 938406
  • 19 + 938387 = 938406
  • 37 + 938369 = 938406
  • 47 + 938359 = 938406
  • 59 + 938347 = 938406
  • 83 + 938323 = 938406
  • 97 + 938309 = 938406
  • 113 + 938293 = 938406

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 938,406 and was likely granted around 1909.

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