Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564046, here are decompositions:

37 + 31564009 = 31564046
67 + 31563979 = 31564046
79 + 31563967 = 31564046
97 + 31563949 = 31564046
103 + 31563943 = 31564046
109 + 31563937 = 31564046
139 + 31563907 = 31564046
229 + 31563817 = 31564046

Showing the first eight; more decompositions exist.
