Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108042, here are decompositions:
- 5 + 108037 = 108042
- 19 + 108023 = 108042
- 29 + 108013 = 108042
- 31 + 108011 = 108042
- 43 + 107999 = 108042
- 61 + 107981 = 108042
- 71 + 107971 = 108042
- 101 + 107941 = 108042
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 108,042 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
