Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143402, here are decompositions:
- 73 + 143329 = 143402
- 139 + 143263 = 143402
- 163 + 143239 = 143402
- 349 + 143053 = 143402
- 409 + 142993 = 143402
- 421 + 142981 = 143402
- 433 + 142969 = 143402
- 439 + 142963 = 143402
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 143,402 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
