Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65742, here are decompositions:

11 + 65731 = 65742
13 + 65729 = 65742
23 + 65719 = 65742
29 + 65713 = 65742
41 + 65701 = 65742
43 + 65699 = 65742
109 + 65633 = 65742
113 + 65629 = 65742

Showing the first eight; more decompositions exist.
