Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942240, here are decompositions:
- 17 + 942223 = 942240
- 23 + 942217 = 942240
- 41 + 942199 = 942240
- 53 + 942187 = 942240
- 71 + 942169 = 942240
- 73 + 942167 = 942240
- 97 + 942143 = 942240
- 127 + 942113 = 942240
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 942,240 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
