Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123770, here are decompositions:
- 13 + 123757 = 123770
- 37 + 123733 = 123770
- 43 + 123727 = 123770
- 103 + 123667 = 123770
- 109 + 123661 = 123770
- 139 + 123631 = 123770
- 151 + 123619 = 123770
- 223 + 123547 = 123770
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 123,770 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
