Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498420, here are decompositions:
- 11 + 498409 = 498420
- 17 + 498403 = 498420
- 19 + 498401 = 498420
- 23 + 498397 = 498420
- 29 + 498391 = 498420
- 53 + 498367 = 498420
- 59 + 498361 = 498420
- 89 + 498331 = 498420
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 498,420 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
