Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566804, here are decompositions:

7 + 31566797 = 31566804
11 + 31566793 = 31566804
41 + 31566763 = 31566804
67 + 31566737 = 31566804
173 + 31566631 = 31566804
193 + 31566611 = 31566804
257 + 31566547 = 31566804
263 + 31566541 = 31566804

Showing the first eight; more decompositions exist.
