Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118742, here are decompositions:
- 3 + 118739 = 118742
- 61 + 118681 = 118742
- 73 + 118669 = 118742
- 109 + 118633 = 118742
- 139 + 118603 = 118742
- 193 + 118549 = 118742
- 199 + 118543 = 118742
- 271 + 118471 = 118742
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 118,742 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
