Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126816, here are decompositions:

59 + 126757 = 126816
73 + 126743 = 126816
83 + 126733 = 126816
97 + 126719 = 126816
103 + 126713 = 126816
113 + 126703 = 126816
163 + 126653 = 126816
233 + 126583 = 126816

Showing the first eight; more decompositions exist.
