Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490378, here are decompositions:

  • 11 + 490367 = 490378
  • 101 + 490277 = 490378
  • 107 + 490271 = 490378
  • 131 + 490247 = 490378
  • 137 + 490241 = 490378
  • 227 + 490151 = 490378
  • 257 + 490121 = 490378
  • 281 + 490097 = 490378

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 490,378 and was likely granted around 1892.

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