Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939520, here are decompositions:

  • 89 + 939431 = 939520
  • 107 + 939413 = 939520
  • 173 + 939347 = 939520
  • 227 + 939293 = 939520
  • 233 + 939287 = 939520
  • 317 + 939203 = 939520
  • 353 + 939167 = 939520
  • 401 + 939119 = 939520

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 939,520 and was likely granted around 1909.

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