Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123670, here are decompositions:
- 3 + 123667 = 123670
- 17 + 123653 = 123670
- 89 + 123581 = 123670
- 167 + 123503 = 123670
- 179 + 123491 = 123670
- 191 + 123479 = 123670
- 251 + 123419 = 123670
- 263 + 123407 = 123670
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 123,670 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
