Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588086, here are decompositions:

67 + 31588019 = 31588086
83 + 31588003 = 31588086
107 + 31587979 = 31588086
137 + 31587949 = 31588086
163 + 31587923 = 31588086
193 + 31587893 = 31588086
227 + 31587859 = 31588086
269 + 31587817 = 31588086

Showing the first eight; more decompositions exist.
