Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101188, here are decompositions:

  • 5 + 101183 = 101188
  • 29 + 101159 = 101188
  • 47 + 101141 = 101188
  • 71 + 101117 = 101188
  • 107 + 101081 = 101188
  • 137 + 101051 = 101188
  • 167 + 101021 = 101188
  • 179 + 101009 = 101188

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 101,188 and was likely granted around 1870.

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