Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686212, here are decompositions:

5 + 8686207 = 8686212
19 + 8686193 = 8686212
23 + 8686189 = 8686212
53 + 8686159 = 8686212
71 + 8686141 = 8686212
89 + 8686123 = 8686212
109 + 8686103 = 8686212
163 + 8686049 = 8686212

Showing the first eight; more decompositions exist.
