Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42816, here are decompositions:

19 + 42797 = 42816
23 + 42793 = 42816
29 + 42787 = 42816
43 + 42773 = 42816
73 + 42743 = 42816
79 + 42737 = 42816
89 + 42727 = 42816
97 + 42719 = 42816

Showing the first eight; more decompositions exist.
