Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65008, here are decompositions:

5 + 65003 = 65008
11 + 64997 = 65008
71 + 64937 = 65008
89 + 64919 = 65008
107 + 64901 = 65008
131 + 64877 = 65008
137 + 64871 = 65008
191 + 64817 = 65008

Showing the first eight; more decompositions exist.
