Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999630, here are decompositions:
- 7 + 999623 = 999630
- 17 + 999613 = 999630
- 19 + 999611 = 999630
- 31 + 999599 = 999630
- 67 + 999563 = 999630
- 89 + 999541 = 999630
- 101 + 999529 = 999630
- 109 + 999521 = 999630
Showing the first eight; more decompositions exist.
