Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582896, here are decompositions:

5 + 31582891 = 31582896
73 + 31582823 = 31582896
139 + 31582757 = 31582896
157 + 31582739 = 31582896
167 + 31582729 = 31582896
223 + 31582673 = 31582896
229 + 31582667 = 31582896
263 + 31582633 = 31582896

Showing the first eight; more decompositions exist.
