Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545120, here are decompositions:
- 3 + 545117 = 545120
- 31 + 545089 = 545120
- 97 + 545023 = 545120
- 157 + 544963 = 545120
- 193 + 544927 = 545120
- 223 + 544897 = 545120
- 241 + 544879 = 545120
- 283 + 544837 = 545120
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 545,120 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
