Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487130, here are decompositions:

  • 19 + 487111 = 487130
  • 31 + 487099 = 487130
  • 37 + 487093 = 487130
  • 73 + 487057 = 487130
  • 79 + 487051 = 487130
  • 109 + 487021 = 487130
  • 139 + 486991 = 487130
  • 181 + 486949 = 487130

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 487,130 and was likely granted around 1892.

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