Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65178, here are decompositions:

5 + 65173 = 65178
7 + 65171 = 65178
11 + 65167 = 65178
31 + 65147 = 65178
37 + 65141 = 65178
59 + 65119 = 65178
67 + 65111 = 65178
79 + 65099 = 65178

Showing the first eight; more decompositions exist.
