Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589994, here are decompositions:

11 + 31589983 = 31589994
13 + 31589981 = 31589994
17 + 31589977 = 31589994
41 + 31589953 = 31589994
71 + 31589923 = 31589994
103 + 31589891 = 31589994
127 + 31589867 = 31589994
151 + 31589843 = 31589994

Showing the first eight; more decompositions exist.
