Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629212, here are decompositions:

13 + 8629199 = 8629212
19 + 8629193 = 8629212
41 + 8629171 = 8629212
43 + 8629169 = 8629212
71 + 8629141 = 8629212
73 + 8629139 = 8629212
89 + 8629123 = 8629212
103 + 8629109 = 8629212

Showing the first eight; more decompositions exist.
