Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51688, here are decompositions:

5 + 51683 = 51688
29 + 51659 = 51688
41 + 51647 = 51688
89 + 51599 = 51688
107 + 51581 = 51688
137 + 51551 = 51688
149 + 51539 = 51688
167 + 51521 = 51688

Showing the first eight; more decompositions exist.
