Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74790, here are decompositions:

11 + 74779 = 74790
19 + 74771 = 74790
29 + 74761 = 74790
31 + 74759 = 74790
43 + 74747 = 74790
59 + 74731 = 74790
61 + 74729 = 74790
71 + 74719 = 74790

Showing the first eight; more decompositions exist.
