Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65528, here are decompositions:

7 + 65521 = 65528
31 + 65497 = 65528
79 + 65449 = 65528
109 + 65419 = 65528
157 + 65371 = 65528
241 + 65287 = 65528
271 + 65257 = 65528
349 + 65179 = 65528

Showing the first eight; more decompositions exist.
