Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588252, here are decompositions:

5 + 31588247 = 31588252
53 + 31588199 = 31588252
149 + 31588103 = 31588252
191 + 31588061 = 31588252
233 + 31588019 = 31588252
359 + 31587893 = 31588252
503 + 31587749 = 31588252
593 + 31587659 = 31588252

Showing the first eight; more decompositions exist.
