Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588092, here are decompositions:

5 + 31588087 = 31588092
31 + 31588061 = 31588092
73 + 31588019 = 31588092
89 + 31588003 = 31588092
113 + 31587979 = 31588092
131 + 31587961 = 31588092
149 + 31587943 = 31588092
181 + 31587911 = 31588092

Showing the first eight; more decompositions exist.
