Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122370, here are decompositions:
- 7 + 122363 = 122370
- 23 + 122347 = 122370
- 43 + 122327 = 122370
- 47 + 122323 = 122370
- 71 + 122299 = 122370
- 97 + 122273 = 122370
- 103 + 122267 = 122370
- 107 + 122263 = 122370
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 122,370 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
