Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65028, here are decompositions:

17 + 65011 = 65028
31 + 64997 = 65028
59 + 64969 = 65028
101 + 64927 = 65028
107 + 64921 = 65028
109 + 64919 = 65028
127 + 64901 = 65028
137 + 64891 = 65028

Showing the first eight; more decompositions exist.
