Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478142, here are decompositions:
- 3 + 478139 = 478142
- 13 + 478129 = 478142
- 31 + 478111 = 478142
- 43 + 478099 = 478142
- 73 + 478069 = 478142
- 79 + 478063 = 478142
- 103 + 478039 = 478142
- 151 + 477991 = 478142
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 478,142 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
