Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702238, here are decompositions:

7 + 8702231 = 8702238
31 + 8702207 = 8702238
59 + 8702179 = 8702238
79 + 8702159 = 8702238
89 + 8702149 = 8702238
101 + 8702137 = 8702238
107 + 8702131 = 8702238
131 + 8702107 = 8702238

Showing the first eight; more decompositions exist.
