Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000920, here are decompositions:
- 13 + 1000907 = 1000920
- 31 + 1000889 = 1000920
- 59 + 1000861 = 1000920
- 61 + 1000859 = 1000920
- 71 + 1000849 = 1000920
- 73 + 1000847 = 1000920
- 127 + 1000793 = 1000920
- 157 + 1000763 = 1000920
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 1,000,920 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
