Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145562, here are decompositions:
- 13 + 145549 = 145562
- 19 + 145543 = 145562
- 31 + 145531 = 145562
- 61 + 145501 = 145562
- 103 + 145459 = 145562
- 139 + 145423 = 145562
- 163 + 145399 = 145562
- 181 + 145381 = 145562
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 145,562 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
