Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588110, here are decompositions:

7 + 31588103 = 31588110
23 + 31588087 = 31588110
107 + 31588003 = 31588110
131 + 31587979 = 31588110
149 + 31587961 = 31588110
167 + 31587943 = 31588110
199 + 31587911 = 31588110
233 + 31587877 = 31588110

Showing the first eight; more decompositions exist.
