Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743824, here are decompositions:

7 + 8743817 = 8743824
17 + 8743807 = 8743824
53 + 8743771 = 8743824
71 + 8743753 = 8743824
107 + 8743717 = 8743824
113 + 8743711 = 8743824
151 + 8743673 = 8743824
191 + 8743633 = 8743824

Showing the first eight; more decompositions exist.
