Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145246, here are decompositions:
- 53 + 145193 = 145246
- 107 + 145139 = 145246
- 113 + 145133 = 145246
- 137 + 145109 = 145246
- 239 + 145007 = 145246
- 263 + 144983 = 145246
- 347 + 144899 = 145246
- 359 + 144887 = 145246
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 145,246 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
