Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145034, here are decompositions:
- 3 + 145031 = 145034
- 13 + 145021 = 145034
- 61 + 144973 = 145034
- 67 + 144967 = 145034
- 73 + 144961 = 145034
- 103 + 144931 = 145034
- 151 + 144883 = 145034
- 271 + 144763 = 145034
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 145,034 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
