Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564088, here are decompositions:

37 + 31564051 = 31564088
79 + 31564009 = 31564088
109 + 31563979 = 31564088
139 + 31563949 = 31564088
151 + 31563937 = 31564088
181 + 31563907 = 31564088
211 + 31563877 = 31564088
271 + 31563817 = 31564088

Showing the first eight; more decompositions exist.
