Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487478, here are decompositions:

  • 7 + 487471 = 487478
  • 31 + 487447 = 487478
  • 97 + 487381 = 487478
  • 367 + 487111 = 487478
  • 379 + 487099 = 487478
  • 421 + 487057 = 487478
  • 457 + 487021 = 487478
  • 487 + 486991 = 487478

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 487,478 and was likely granted around 1892.

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