Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581162, here are decompositions:

  • 13 + 581149 = 581162
  • 19 + 581143 = 581162
  • 61 + 581101 = 581162
  • 73 + 581089 = 581162
  • 181 + 580981 = 581162
  • 193 + 580969 = 581162
  • 223 + 580939 = 581162
  • 271 + 580891 = 581162

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 581,162 and was likely granted around 1896.

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