Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599566, here are decompositions:

3 + 31599563 = 31599566
13 + 31599553 = 31599566
67 + 31599499 = 31599566
79 + 31599487 = 31599566
127 + 31599439 = 31599566
307 + 31599259 = 31599566
373 + 31599193 = 31599566
409 + 31599157 = 31599566

Showing the first eight; more decompositions exist.
