Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65838, here are decompositions:

7 + 65831 = 65838
11 + 65827 = 65838
29 + 65809 = 65838
61 + 65777 = 65838
107 + 65731 = 65838
109 + 65729 = 65838
131 + 65707 = 65838
137 + 65701 = 65838

Showing the first eight; more decompositions exist.
