Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120742, here are decompositions:
- 3 + 120739 = 120742
- 5 + 120737 = 120742
- 29 + 120713 = 120742
- 53 + 120689 = 120742
- 71 + 120671 = 120742
- 101 + 120641 = 120742
- 173 + 120569 = 120742
- 179 + 120563 = 120742
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 120,742 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
