Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126620, here are decompositions:
- 7 + 126613 = 126620
- 19 + 126601 = 126620
- 37 + 126583 = 126620
- 73 + 126547 = 126620
- 79 + 126541 = 126620
- 103 + 126517 = 126620
- 127 + 126493 = 126620
- 139 + 126481 = 126620
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 126,620 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
