Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51236, here are decompositions:

7 + 51229 = 51236
19 + 51217 = 51236
37 + 51199 = 51236
43 + 51193 = 51236
67 + 51169 = 51236
79 + 51157 = 51236
103 + 51133 = 51236
127 + 51109 = 51236

Showing the first eight; more decompositions exist.
