Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522130, here are decompositions:
- 3 + 522127 = 522130
- 17 + 522113 = 522130
- 47 + 522083 = 522130
- 71 + 522059 = 522130
- 83 + 522047 = 522130
- 113 + 522017 = 522130
- 131 + 521999 = 522130
- 137 + 521993 = 522130
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 522,130 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
