Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000864, here are decompositions:
- 3 + 1000861 = 1000864
- 5 + 1000859 = 1000864
- 17 + 1000847 = 1000864
- 71 + 1000793 = 1000864
- 101 + 1000763 = 1000864
- 167 + 1000697 = 1000864
- 173 + 1000691 = 1000864
- 197 + 1000667 = 1000864
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 1,000,864 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
