Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985218, here are decompositions:

5 + 985213 = 985218
37 + 985181 = 985218
41 + 985177 = 985218
67 + 985151 = 985218
89 + 985129 = 985218
97 + 985121 = 985218
109 + 985109 = 985218
139 + 985079 = 985218

Showing the first eight; more decompositions exist.
