Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65508, here are decompositions:

11 + 65497 = 65508
29 + 65479 = 65508
59 + 65449 = 65508
61 + 65447 = 65508
71 + 65437 = 65508
89 + 65419 = 65508
101 + 65407 = 65508
127 + 65381 = 65508

Showing the first eight; more decompositions exist.
