Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000656, here are decompositions:
- 5 + 1000651 = 1000656
- 17 + 1000639 = 1000656
- 37 + 1000619 = 1000656
- 47 + 1000609 = 1000656
- 67 + 1000589 = 1000656
- 79 + 1000577 = 1000656
- 109 + 1000547 = 1000656
- 149 + 1000507 = 1000656
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 1,000,656 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
