Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180264, here are decompositions:
- 5 + 180259 = 180264
- 17 + 180247 = 180264
- 23 + 180241 = 180264
- 31 + 180233 = 180264
- 43 + 180221 = 180264
- 53 + 180211 = 180264
- 83 + 180181 = 180264
- 103 + 180161 = 180264
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 180,264 and was likely granted around 1875.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
