Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588116, here are decompositions:

13 + 31588103 = 31588116
29 + 31588087 = 31588116
97 + 31588019 = 31588116
113 + 31588003 = 31588116
137 + 31587979 = 31588116
167 + 31587949 = 31588116
173 + 31587943 = 31588116
193 + 31587923 = 31588116

Showing the first eight; more decompositions exist.
