Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120880, here are decompositions:
- 3 + 120877 = 120880
- 17 + 120863 = 120880
- 29 + 120851 = 120880
- 47 + 120833 = 120880
- 101 + 120779 = 120880
- 113 + 120767 = 120880
- 131 + 120749 = 120880
- 167 + 120713 = 120880
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 120,880 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
