Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588050, here are decompositions:

31 + 31588019 = 31588050
47 + 31588003 = 31588050
71 + 31587979 = 31588050
89 + 31587961 = 31588050
101 + 31587949 = 31588050
107 + 31587943 = 31588050
127 + 31587923 = 31588050
139 + 31587911 = 31588050

Showing the first eight; more decompositions exist.
