Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158130, here are decompositions:

  • 17 + 158113 = 158130
  • 53 + 158077 = 158130
  • 59 + 158071 = 158130
  • 83 + 158047 = 158130
  • 101 + 158029 = 158130
  • 113 + 158017 = 158130
  • 127 + 158003 = 158130
  • 131 + 157999 = 158130

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 158,130 and was likely granted around 1873.

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