Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748216, here are decompositions:

7 + 8748209 = 8748216
13 + 8748203 = 8748216
17 + 8748199 = 8748216
73 + 8748143 = 8748216
79 + 8748137 = 8748216
107 + 8748109 = 8748216
173 + 8748043 = 8748216
199 + 8748017 = 8748216

Showing the first eight; more decompositions exist.
