Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578816, here are decompositions:

  • 13 + 578803 = 578816
  • 37 + 578779 = 578816
  • 97 + 578719 = 578816
  • 127 + 578689 = 578816
  • 157 + 578659 = 578816
  • 229 + 578587 = 578816
  • 283 + 578533 = 578816
  • 307 + 578509 = 578816

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 578,816 and was likely granted around 1896.

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