Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000688, here are decompositions:
- 19 + 1000669 = 1000688
- 37 + 1000651 = 1000688
- 67 + 1000621 = 1000688
- 79 + 1000609 = 1000688
- 109 + 1000579 = 1000688
- 151 + 1000537 = 1000688
- 181 + 1000507 = 1000688
- 307 + 1000381 = 1000688
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 1,000,688 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
