Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743818, here are decompositions:

11 + 8743807 = 8743818
47 + 8743771 = 8743818
71 + 8743747 = 8743818
101 + 8743717 = 8743818
107 + 8743711 = 8743818
137 + 8743681 = 8743818
179 + 8743639 = 8743818
197 + 8743621 = 8743818

Showing the first eight; more decompositions exist.
