Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158980, here are decompositions:

  • 53 + 158927 = 158980
  • 71 + 158909 = 158980
  • 113 + 158867 = 158980
  • 131 + 158849 = 158980
  • 137 + 158843 = 158980
  • 233 + 158747 = 158980
  • 281 + 158699 = 158980
  • 317 + 158663 = 158980

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 158,980 and was likely granted around 1873.

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