Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190278, here are decompositions:

  • 7 + 190271 = 190278
  • 17 + 190261 = 190278
  • 29 + 190249 = 190278
  • 71 + 190207 = 190278
  • 97 + 190181 = 190278
  • 131 + 190147 = 190278
  • 149 + 190129 = 190278
  • 157 + 190121 = 190278

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 190,278 and was likely granted around 1875.

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