Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564060, here are decompositions:

71 + 31563989 = 31564060
107 + 31563953 = 31564060
113 + 31563947 = 31564060
131 + 31563929 = 31564060
149 + 31563911 = 31564060
179 + 31563881 = 31564060
197 + 31563863 = 31564060
233 + 31563827 = 31564060

Showing the first eight; more decompositions exist.
