Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509688, here are decompositions:
- 7 + 509681 = 509688
- 29 + 509659 = 509688
- 41 + 509647 = 509688
- 97 + 509591 = 509688
- 107 + 509581 = 509688
- 131 + 509557 = 509688
- 139 + 509549 = 509688
- 167 + 509521 = 509688
Showing the first eight; more decompositions exist.
