Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143102, here are decompositions:
- 109 + 142993 = 143102
- 139 + 142963 = 143102
- 163 + 142939 = 143102
- 199 + 142903 = 143102
- 229 + 142873 = 143102
- 313 + 142789 = 143102
- 331 + 142771 = 143102
- 601 + 142501 = 143102
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 143,102 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
