Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478170, here are decompositions:
- 13 + 478157 = 478170
- 31 + 478139 = 478170
- 41 + 478129 = 478170
- 59 + 478111 = 478170
- 71 + 478099 = 478170
- 83 + 478087 = 478170
- 101 + 478069 = 478170
- 103 + 478067 = 478170
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 478,170 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
