Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581122, here are decompositions:

  • 23 + 581099 = 581122
  • 53 + 581069 = 581122
  • 233 + 580889 = 581122
  • 251 + 580871 = 581122
  • 263 + 580859 = 581122
  • 359 + 580763 = 581122
  • 389 + 580733 = 581122
  • 431 + 580691 = 581122

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 581,122 and was likely granted around 1896.

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