Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000020, here are decompositions:
- 17 + 1000003 = 1000020
- 37 + 999983 = 1000020
- 41 + 999979 = 1000020
- 59 + 999961 = 1000020
- 61 + 999959 = 1000020
- 67 + 999953 = 1000020
- 89 + 999931 = 1000020
- 103 + 999917 = 1000020
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 1,000,020 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
