Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51658, here are decompositions:

11 + 51647 = 51658
59 + 51599 = 51658
107 + 51551 = 51658
137 + 51521 = 51658
179 + 51479 = 51658
197 + 51461 = 51658
227 + 51431 = 51658
239 + 51419 = 51658

Showing the first eight; more decompositions exist.
