Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143000, here are decompositions:
- 7 + 142993 = 143000
- 19 + 142981 = 143000
- 31 + 142969 = 143000
- 37 + 142963 = 143000
- 61 + 142939 = 143000
- 97 + 142903 = 143000
- 103 + 142897 = 143000
- 127 + 142873 = 143000
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 143,000 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
