Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66368, here are decompositions:

7 + 66361 = 66368
31 + 66337 = 66368
67 + 66301 = 66368
97 + 66271 = 66368
199 + 66169 = 66368
331 + 66037 = 66368
439 + 65929 = 66368
487 + 65881 = 66368

Showing the first eight; more decompositions exist.
