Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534566, here are decompositions:

5 + 31534561 = 31534566
13 + 31534553 = 31534566
23 + 31534543 = 31534566
73 + 31534493 = 31534566
79 + 31534487 = 31534566
83 + 31534483 = 31534566
109 + 31534457 = 31534566
137 + 31534429 = 31534566

Showing the first eight; more decompositions exist.
