Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564050, here are decompositions:

41 + 31564009 = 31564050
61 + 31563989 = 31564050
71 + 31563979 = 31564050
83 + 31563967 = 31564050
97 + 31563953 = 31564050
101 + 31563949 = 31564050
103 + 31563947 = 31564050
107 + 31563943 = 31564050

Showing the first eight; more decompositions exist.
