Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999788, here are decompositions:
- 19 + 999769 = 999788
- 61 + 999727 = 999788
- 67 + 999721 = 999788
- 157 + 999631 = 999788
- 337 + 999451 = 999788
- 457 + 999331 = 999788
- 571 + 999217 = 999788
- 607 + 999181 = 999788
Showing the first eight; more decompositions exist.
