Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157380, here are decompositions:

  • 17 + 157363 = 157380
  • 29 + 157351 = 157380
  • 31 + 157349 = 157380
  • 53 + 157327 = 157380
  • 59 + 157321 = 157380
  • 73 + 157307 = 157380
  • 89 + 157291 = 157380
  • 101 + 157279 = 157380

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 157,380 and was likely granted around 1873.

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