Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045200, here are decompositions:
- 7 + 1045193 = 1045200
- 17 + 1045183 = 1045200
- 43 + 1045157 = 1045200
- 47 + 1045153 = 1045200
- 71 + 1045129 = 1045200
- 83 + 1045117 = 1045200
- 89 + 1045111 = 1045200
- 137 + 1045063 = 1045200
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 1,045,200 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
