Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523438, here are decompositions:

  • 5 + 523433 = 523438
  • 11 + 523427 = 523438
  • 89 + 523349 = 523438
  • 131 + 523307 = 523438
  • 269 + 523169 = 523438
  • 389 + 523049 = 523438
  • 431 + 523007 = 523438
  • 449 + 522989 = 523438

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 523,438 and was likely granted around 1894.

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