Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157270, here are decompositions:

  • 11 + 157259 = 157270
  • 17 + 157253 = 157270
  • 23 + 157247 = 157270
  • 41 + 157229 = 157270
  • 53 + 157217 = 157270
  • 59 + 157211 = 157270
  • 89 + 157181 = 157270
  • 107 + 157163 = 157270

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 157,270 and was likely granted around 1873.

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