Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521416, here are decompositions:

  • 17 + 521399 = 521416
  • 23 + 521393 = 521416
  • 47 + 521369 = 521416
  • 53 + 521363 = 521416
  • 59 + 521357 = 521416
  • 107 + 521309 = 521416
  • 149 + 521267 = 521416
  • 173 + 521243 = 521416

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 521,416 and was likely granted around 1894.

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