Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581604, here are decompositions:

  • 5 + 581599 = 581604
  • 7 + 581597 = 581604
  • 31 + 581573 = 581604
  • 47 + 581557 = 581604
  • 53 + 581551 = 581604
  • 83 + 581521 = 581604
  • 113 + 581491 = 581604
  • 131 + 581473 = 581604

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 581,604 and was likely granted around 1896.

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