Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51356, here are decompositions:

7 + 51349 = 51356
13 + 51343 = 51356
73 + 51283 = 51356
127 + 51229 = 51356
139 + 51217 = 51356
157 + 51199 = 51356
163 + 51193 = 51356
199 + 51157 = 51356

Showing the first eight; more decompositions exist.
