Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624566, here are decompositions:

7 + 31624559 = 31624566
19 + 31624547 = 31624566
59 + 31624507 = 31624566
89 + 31624477 = 31624566
109 + 31624457 = 31624566
137 + 31624429 = 31624566
179 + 31624387 = 31624566
199 + 31624367 = 31624566

Showing the first eight; more decompositions exist.
