Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159158, here are decompositions:

  • 61 + 159097 = 159158
  • 79 + 159079 = 159158
  • 199 + 158959 = 159158
  • 277 + 158881 = 159158
  • 367 + 158791 = 159158
  • 397 + 158761 = 159158
  • 409 + 158749 = 159158
  • 541 + 158617 = 159158

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 159,158 and was likely granted around 1873.

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