Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588026, here are decompositions:

7 + 31588019 = 31588026
23 + 31588003 = 31588026
47 + 31587979 = 31588026
83 + 31587943 = 31588026
103 + 31587923 = 31588026
149 + 31587877 = 31588026
167 + 31587859 = 31588026
227 + 31587799 = 31588026

Showing the first eight; more decompositions exist.
