Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143156, here are decompositions:
- 19 + 143137 = 143156
- 43 + 143113 = 143156
- 103 + 143053 = 143156
- 163 + 142993 = 143156
- 193 + 142963 = 143156
- 283 + 142873 = 143156
- 367 + 142789 = 143156
- 397 + 142759 = 143156
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 143,156 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
