Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65790, here are decompositions:

13 + 65777 = 65790
29 + 65761 = 65790
59 + 65731 = 65790
61 + 65729 = 65790
71 + 65719 = 65790
73 + 65717 = 65790
83 + 65707 = 65790
89 + 65701 = 65790

Showing the first eight; more decompositions exist.
