Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100042, here are decompositions:
- 23 + 100019 = 100042
- 53 + 99989 = 100042
- 71 + 99971 = 100042
- 113 + 99929 = 100042
- 233 + 99809 = 100042
- 281 + 99761 = 100042
- 353 + 99689 = 100042
- 419 + 99623 = 100042
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 100,042 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
