Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51648, here are decompositions:

11 + 51637 = 51648
17 + 51631 = 51648
41 + 51607 = 51648
67 + 51581 = 51648
71 + 51577 = 51648
97 + 51551 = 51648
109 + 51539 = 51648
127 + 51521 = 51648

Showing the first eight; more decompositions exist.
