Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566846, here are decompositions:

7 + 31566839 = 31566846
19 + 31566827 = 31566846
29 + 31566817 = 31566846
43 + 31566803 = 31566846
53 + 31566793 = 31566846
83 + 31566763 = 31566846
97 + 31566749 = 31566846
109 + 31566737 = 31566846

Showing the first eight; more decompositions exist.
