Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65648, here are decompositions:

19 + 65629 = 65648
31 + 65617 = 65648
61 + 65587 = 65648
67 + 65581 = 65648
97 + 65551 = 65648
109 + 65539 = 65648
127 + 65521 = 65648
151 + 65497 = 65648

Showing the first eight; more decompositions exist.
