Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588032, here are decompositions:

13 + 31588019 = 31588032
29 + 31588003 = 31588032
53 + 31587979 = 31588032
71 + 31587961 = 31588032
83 + 31587949 = 31588032
89 + 31587943 = 31588032
109 + 31587923 = 31588032
139 + 31587893 = 31588032

Showing the first eight; more decompositions exist.
