Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578660, here are decompositions:

  • 13 + 578647 = 578660
  • 73 + 578587 = 578660
  • 79 + 578581 = 578660
  • 97 + 578563 = 578660
  • 127 + 578533 = 578660
  • 151 + 578509 = 578660
  • 157 + 578503 = 578660
  • 163 + 578497 = 578660

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 578,660 and was likely granted around 1896.

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