Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999468, here are decompositions:
- 17 + 999451 = 999468
- 31 + 999437 = 999468
- 37 + 999431 = 999468
- 79 + 999389 = 999468
- 97 + 999371 = 999468
- 109 + 999359 = 999468
- 137 + 999331 = 999468
- 139 + 999329 = 999468
Showing the first eight; more decompositions exist.
