Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743782, here are decompositions:

11 + 8743771 = 8743782
13 + 8743769 = 8743782
29 + 8743753 = 8743782
71 + 8743711 = 8743782
101 + 8743681 = 8743782
109 + 8743673 = 8743782
149 + 8743633 = 8743782
193 + 8743589 = 8743782

Showing the first eight; more decompositions exist.
