Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653212, here are decompositions:

5 + 8653207 = 8653212
13 + 8653199 = 8653212
41 + 8653171 = 8653212
101 + 8653111 = 8653212
109 + 8653103 = 8653212
131 + 8653081 = 8653212
149 + 8653063 = 8653212
181 + 8653031 = 8653212

Showing the first eight; more decompositions exist.
