Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743784, here are decompositions:

13 + 8743771 = 8743784
31 + 8743753 = 8743784
37 + 8743747 = 8743784
67 + 8743717 = 8743784
73 + 8743711 = 8743784
103 + 8743681 = 8743784
151 + 8743633 = 8743784
163 + 8743621 = 8743784

Showing the first eight; more decompositions exist.
