Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101142, here are decompositions:
- 23 + 101119 = 101142
- 29 + 101113 = 101142
- 31 + 101111 = 101142
- 53 + 101089 = 101142
- 61 + 101081 = 101142
- 79 + 101063 = 101142
- 199 + 100943 = 101142
- 211 + 100931 = 101142
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 101,142 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
