Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65142, here are decompositions:

13 + 65129 = 65142
19 + 65123 = 65142
23 + 65119 = 65142
31 + 65111 = 65142
41 + 65101 = 65142
43 + 65099 = 65142
53 + 65089 = 65142
71 + 65071 = 65142

Showing the first eight; more decompositions exist.
