Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541780, here are decompositions:

  • 3 + 541777 = 541780
  • 17 + 541763 = 541780
  • 53 + 541727 = 541780
  • 59 + 541721 = 541780
  • 149 + 541631 = 541780
  • 167 + 541613 = 541780
  • 191 + 541589 = 541780
  • 233 + 541547 = 541780

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 541,780 and was likely granted around 1895.

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