Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120782, here are decompositions:
- 3 + 120779 = 120782
- 19 + 120763 = 120782
- 43 + 120739 = 120782
- 61 + 120721 = 120782
- 73 + 120709 = 120782
- 163 + 120619 = 120782
- 271 + 120511 = 120782
- 433 + 120349 = 120782
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 120,782 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
