Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588134, here are decompositions:

5 + 31588129 = 31588134
31 + 31588103 = 31588134
47 + 31588087 = 31588134
73 + 31588061 = 31588134
131 + 31588003 = 31588134
173 + 31587961 = 31588134
191 + 31587943 = 31588134
211 + 31587923 = 31588134

Showing the first eight; more decompositions exist.
