Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65088, here are decompositions:

17 + 65071 = 65088
59 + 65029 = 65088
61 + 65027 = 65088
137 + 64951 = 65088
151 + 64937 = 65088
167 + 64921 = 65088
197 + 64891 = 65088
211 + 64877 = 65088

Showing the first eight; more decompositions exist.
