Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146440, here are decompositions:
- 3 + 146437 = 146440
- 17 + 146423 = 146440
- 23 + 146417 = 146440
- 59 + 146381 = 146440
- 71 + 146369 = 146440
- 131 + 146309 = 146440
- 149 + 146291 = 146440
- 167 + 146273 = 146440
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 146,440 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
