Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588022, here are decompositions:

3 + 31588019 = 31588022
19 + 31588003 = 31588022
43 + 31587979 = 31588022
61 + 31587961 = 31588022
73 + 31587949 = 31588022
79 + 31587943 = 31588022
163 + 31587859 = 31588022
223 + 31587799 = 31588022

Showing the first eight; more decompositions exist.
