Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961788, here are decompositions:

5 + 961783 = 961788
11 + 961777 = 961788
19 + 961769 = 961788
31 + 961757 = 961788
41 + 961747 = 961788
59 + 961729 = 961788
97 + 961691 = 961788
101 + 961687 = 961788

Showing the first eight; more decompositions exist.
