Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519438, here are decompositions:

  • 5 + 519433 = 519438
  • 11 + 519427 = 519438
  • 47 + 519391 = 519438
  • 67 + 519371 = 519438
  • 79 + 519359 = 519438
  • 89 + 519349 = 519438
  • 131 + 519307 = 519438
  • 137 + 519301 = 519438

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 519,438 and was likely granted around 1894.

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