Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487142, here are decompositions:

  • 31 + 487111 = 487142
  • 43 + 487099 = 487142
  • 151 + 486991 = 487142
  • 193 + 486949 = 487142
  • 199 + 486943 = 487142
  • 373 + 486769 = 487142
  • 421 + 486721 = 487142
  • 463 + 486679 = 487142

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 487,142 and was likely granted around 1892.

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