Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123816, here are decompositions:

13 + 123803 = 123816
29 + 123787 = 123816
59 + 123757 = 123816
79 + 123737 = 123816
83 + 123733 = 123816
89 + 123727 = 123816
97 + 123719 = 123816
109 + 123707 = 123816

Showing the first eight; more decompositions exist.
