Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65532, here are decompositions:

11 + 65521 = 65532
13 + 65519 = 65532
53 + 65479 = 65532
83 + 65449 = 65532
109 + 65423 = 65532
113 + 65419 = 65532
139 + 65393 = 65532
151 + 65381 = 65532

Showing the first eight; more decompositions exist.
