Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647824, here are decompositions:

5 + 8647819 = 8647824
7 + 8647817 = 8647824
23 + 8647801 = 8647824
41 + 8647783 = 8647824
71 + 8647753 = 8647824
113 + 8647711 = 8647824
127 + 8647697 = 8647824
167 + 8647657 = 8647824

Showing the first eight; more decompositions exist.
