Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564098, here are decompositions:

19 + 31564079 = 31564098
47 + 31564051 = 31564098
89 + 31564009 = 31564098
109 + 31563989 = 31564098
131 + 31563967 = 31564098
149 + 31563949 = 31564098
151 + 31563947 = 31564098
157 + 31563941 = 31564098

Showing the first eight; more decompositions exist.
