Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105150, here are decompositions:
- 7 + 105143 = 105150
- 13 + 105137 = 105150
- 43 + 105107 = 105150
- 53 + 105097 = 105150
- 79 + 105071 = 105150
- 113 + 105037 = 105150
- 127 + 105023 = 105150
- 131 + 105019 = 105150
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105 150 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
