Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65538, here are decompositions:

17 + 65521 = 65538
19 + 65519 = 65538
41 + 65497 = 65538
59 + 65479 = 65538
89 + 65449 = 65538
101 + 65437 = 65538
131 + 65407 = 65538
157 + 65381 = 65538

Showing the first eight; more decompositions exist.
