Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712216, here are decompositions:

43 + 8712173 = 8712216
47 + 8712169 = 8712216
53 + 8712163 = 8712216
59 + 8712157 = 8712216
67 + 8712149 = 8712216
83 + 8712133 = 8712216
103 + 8712113 = 8712216
157 + 8712059 = 8712216

Showing the first eight; more decompositions exist.
