Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65986, here are decompositions:

3 + 65983 = 65986
5 + 65981 = 65986
23 + 65963 = 65986
29 + 65957 = 65986
59 + 65927 = 65986
149 + 65837 = 65986
197 + 65789 = 65986
257 + 65729 = 65986

Showing the first eight; more decompositions exist.
