Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122558, here are decompositions:
- 31 + 122527 = 122558
- 61 + 122497 = 122558
- 109 + 122449 = 122558
- 157 + 122401 = 122558
- 211 + 122347 = 122558
- 307 + 122251 = 122558
- 349 + 122209 = 122558
- 409 + 122149 = 122558
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 122,558 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
