Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51216, here are decompositions:

13 + 51203 = 51216
17 + 51199 = 51216
19 + 51197 = 51216
23 + 51193 = 51216
47 + 51169 = 51216
59 + 51157 = 51216
79 + 51137 = 51216
83 + 51133 = 51216

Showing the first eight; more decompositions exist.
