Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566022, here are decompositions:

3 + 31566019 = 31566022
29 + 31565993 = 31566022
41 + 31565981 = 31566022
53 + 31565969 = 31566022
251 + 31565771 = 31566022
359 + 31565663 = 31566022
419 + 31565603 = 31566022
461 + 31565561 = 31566022

Showing the first eight; more decompositions exist.
