Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105042, here are decompositions:
- 5 + 105037 = 105042
- 11 + 105031 = 105042
- 19 + 105023 = 105042
- 23 + 105019 = 105042
- 43 + 104999 = 105042
- 71 + 104971 = 105042
- 83 + 104959 = 105042
- 89 + 104953 = 105042
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 105.042 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
