Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000420, here are decompositions:
- 11 + 1000409 = 1000420
- 17 + 1000403 = 1000420
- 23 + 1000397 = 1000420
- 53 + 1000367 = 1000420
- 107 + 1000313 = 1000420
- 131 + 1000289 = 1000420
- 167 + 1000253 = 1000420
- 227 + 1000193 = 1000420
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 1,000,420 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
