Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581016, here are decompositions:

  • 19 + 580997 = 581016
  • 47 + 580969 = 581016
  • 89 + 580927 = 581016
  • 97 + 580919 = 581016
  • 103 + 580913 = 581016
  • 127 + 580889 = 581016
  • 157 + 580859 = 581016
  • 173 + 580843 = 581016

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 581,016 and was likely granted around 1896.

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