Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158988, here are decompositions:

  • 7 + 158981 = 158988
  • 29 + 158959 = 158988
  • 47 + 158941 = 158988
  • 61 + 158927 = 158988
  • 79 + 158909 = 158988
  • 107 + 158881 = 158988
  • 139 + 158849 = 158988
  • 197 + 158791 = 158988

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 158,988 and was likely granted around 1873.

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