Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588112, here are decompositions:

109 + 31588003 = 31588112
151 + 31587961 = 31588112
163 + 31587949 = 31588112
313 + 31587799 = 31588112
331 + 31587781 = 31588112
691 + 31587421 = 31588112
823 + 31587289 = 31588112
1021 + 31587091 = 31588112

Showing the first eight; more decompositions exist.
