Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51650, here are decompositions:
- 3 + 51647 = 51650
- 13 + 51637 = 51650
- 19 + 51631 = 51650
- 37 + 51613 = 51650
- 43 + 51607 = 51650
- 73 + 51577 = 51650
- 139 + 51511 = 51650
- 163 + 51487 = 51650
Showing the first eight; more decompositions exist.
