Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566844, here are decompositions:

5 + 31566839 = 31566844
17 + 31566827 = 31566844
41 + 31566803 = 31566844
47 + 31566797 = 31566844
107 + 31566737 = 31566844
131 + 31566713 = 31566844
233 + 31566611 = 31566844
317 + 31566527 = 31566844

Showing the first eight; more decompositions exist.
