Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713218, here are decompositions:

5 + 8713213 = 8713218
37 + 8713181 = 8713218
61 + 8713157 = 8713218
97 + 8713121 = 8713218
109 + 8713109 = 8713218
131 + 8713087 = 8713218
149 + 8713069 = 8713218
167 + 8713051 = 8713218

Showing the first eight; more decompositions exist.
