Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130000, here are decompositions:
- 29 + 129971 = 130000
- 41 + 129959 = 130000
- 47 + 129953 = 130000
- 83 + 129917 = 130000
- 107 + 129893 = 130000
- 113 + 129887 = 130000
- 197 + 129803 = 130000
- 251 + 129749 = 130000
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 130,000 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
