Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718222, here are decompositions:

5 + 8718217 = 8718222
31 + 8718191 = 8718222
59 + 8718163 = 8718222
109 + 8718113 = 8718222
113 + 8718109 = 8718222
131 + 8718091 = 8718222
179 + 8718043 = 8718222
211 + 8718011 = 8718222

Showing the first eight; more decompositions exist.
