Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145150, here are decompositions:
- 11 + 145139 = 145150
- 17 + 145133 = 145150
- 29 + 145121 = 145150
- 41 + 145109 = 145150
- 59 + 145091 = 145150
- 107 + 145043 = 145150
- 113 + 145037 = 145150
- 167 + 144983 = 145150
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 145,150 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
