Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715212, here are decompositions:

3 + 8715209 = 8715212
19 + 8715193 = 8715212
31 + 8715181 = 8715212
61 + 8715151 = 8715212
109 + 8715103 = 8715212
193 + 8715019 = 8715212
199 + 8715013 = 8715212
223 + 8714989 = 8715212

Showing the first eight; more decompositions exist.
