Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525356, here are decompositions:

13 + 31525343 = 31525356
67 + 31525289 = 31525356
73 + 31525283 = 31525356
89 + 31525267 = 31525356
113 + 31525243 = 31525356
127 + 31525229 = 31525356
173 + 31525183 = 31525356
179 + 31525177 = 31525356

Showing the first eight; more decompositions exist.
