Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149150, here are decompositions:
- 7 + 149143 = 149150
- 31 + 149119 = 149150
- 37 + 149113 = 149150
- 73 + 149077 = 149150
- 97 + 149053 = 149150
- 139 + 149011 = 149150
- 193 + 148957 = 149150
- 223 + 148927 = 149150
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 149,150 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
