Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144040, here are decompositions:
- 3 + 144037 = 144040
- 41 + 143999 = 144040
- 59 + 143981 = 144040
- 131 + 143909 = 144040
- 167 + 143873 = 144040
- 227 + 143813 = 144040
- 233 + 143807 = 144040
- 311 + 143729 = 144040
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 144,040 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
