Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51218, here are decompositions:

19 + 51199 = 51218
61 + 51157 = 51218
67 + 51151 = 51218
109 + 51109 = 51218
157 + 51061 = 51218
229 + 50989 = 51218
379 + 50839 = 51218
397 + 50821 = 51218

Showing the first eight; more decompositions exist.
