Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133712, here are decompositions:
- 3 + 133709 = 133712
- 43 + 133669 = 133712
- 79 + 133633 = 133712
- 193 + 133519 = 133712
- 409 + 133303 = 133712
- 433 + 133279 = 133712
- 499 + 133213 = 133712
- 643 + 133069 = 133712
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 133,712 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
