Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130790, here are decompositions:
- 3 + 130787 = 130790
- 7 + 130783 = 130790
- 61 + 130729 = 130790
- 97 + 130693 = 130790
- 103 + 130687 = 130790
- 109 + 130681 = 130790
- 139 + 130651 = 130790
- 151 + 130639 = 130790
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 130,790 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
