Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149240, here are decompositions:
- 43 + 149197 = 149240
- 67 + 149173 = 149240
- 79 + 149161 = 149240
- 97 + 149143 = 149240
- 127 + 149113 = 149240
- 139 + 149101 = 149240
- 163 + 149077 = 149240
- 181 + 149059 = 149240
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 149,240 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
