Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945442, here are decompositions:
- 11 + 945431 = 945442
- 53 + 945389 = 945442
- 83 + 945359 = 945442
- 101 + 945341 = 945442
- 149 + 945293 = 945442
- 233 + 945209 = 945442
- 263 + 945179 = 945442
- 353 + 945089 = 945442
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 945,442 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
