Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525584, here are decompositions:

17 + 31525567 = 31525584
31 + 31525553 = 31525584
47 + 31525537 = 31525584
107 + 31525477 = 31525584
137 + 31525447 = 31525584
163 + 31525421 = 31525584
241 + 31525343 = 31525584
317 + 31525267 = 31525584

Showing the first eight; more decompositions exist.
