Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637216, here are decompositions:

13 + 8637203 = 8637216
37 + 8637179 = 8637216
53 + 8637163 = 8637216
83 + 8637133 = 8637216
97 + 8637119 = 8637216
109 + 8637107 = 8637216
113 + 8637103 = 8637216
149 + 8637067 = 8637216

Showing the first eight; more decompositions exist.
