Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149426, here are decompositions:
- 3 + 149423 = 149426
- 7 + 149419 = 149426
- 103 + 149323 = 149426
- 139 + 149287 = 149426
- 157 + 149269 = 149426
- 229 + 149197 = 149426
- 283 + 149143 = 149426
- 307 + 149119 = 149426
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 149,426 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
