Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65878, here are decompositions:

11 + 65867 = 65878
41 + 65837 = 65878
47 + 65831 = 65878
89 + 65789 = 65878
101 + 65777 = 65878
149 + 65729 = 65878
179 + 65699 = 65878
191 + 65687 = 65878

Showing the first eight; more decompositions exist.
