Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162042, here are decompositions:
- 31 + 162011 = 162042
- 43 + 161999 = 162042
- 59 + 161983 = 162042
- 71 + 161971 = 162042
- 73 + 161969 = 162042
- 131 + 161911 = 162042
- 163 + 161879 = 162042
- 173 + 161869 = 162042
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 162,042 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
