Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170430, here are decompositions:
- 17 + 170413 = 170430
- 37 + 170393 = 170430
- 41 + 170389 = 170430
- 47 + 170383 = 170430
- 59 + 170371 = 170430
- 61 + 170369 = 170430
- 67 + 170363 = 170430
- 79 + 170351 = 170430
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 170,430 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
