Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522120, here are decompositions:
- 7 + 522113 = 522120
- 37 + 522083 = 522120
- 41 + 522079 = 522120
- 47 + 522073 = 522120
- 59 + 522061 = 522120
- 61 + 522059 = 522120
- 73 + 522047 = 522120
- 83 + 522037 = 522120
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 522,120 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
