Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487020, here are decompositions:

  • 7 + 487013 = 487020
  • 13 + 487007 = 487020
  • 29 + 486991 = 487020
  • 43 + 486977 = 487020
  • 71 + 486949 = 487020
  • 73 + 486947 = 487020
  • 97 + 486923 = 487020
  • 113 + 486907 = 487020

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 487,020 and was likely granted around 1892.

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