Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105156, here are decompositions:

  • 13 + 105143 = 105156
  • 19 + 105137 = 105156
  • 59 + 105097 = 105156
  • 137 + 105019 = 105156
  • 157 + 104999 = 105156
  • 197 + 104959 = 105156
  • 223 + 104933 = 105156
  • 239 + 104917 = 105156

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 105.156 and was likely granted around 1870.

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