Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51838, here are decompositions:

11 + 51827 = 51838
41 + 51797 = 51838
71 + 51767 = 51838
89 + 51749 = 51838
179 + 51659 = 51838
191 + 51647 = 51838
239 + 51599 = 51838
257 + 51581 = 51838

Showing the first eight; more decompositions exist.
