Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513072, here are decompositions:

  • 5 + 513067 = 513072
  • 13 + 513059 = 513072
  • 19 + 513053 = 513072
  • 31 + 513041 = 513072
  • 41 + 513031 = 513072
  • 59 + 513013 = 513072
  • 71 + 513001 = 513072
  • 73 + 512999 = 513072

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 513,072 and was likely granted around 1893.

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