Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584976, here are decompositions:

23 + 31584953 = 31584976
29 + 31584947 = 31584976
89 + 31584887 = 31584976
107 + 31584869 = 31584976
167 + 31584809 = 31584976
179 + 31584797 = 31584976
263 + 31584713 = 31584976
359 + 31584617 = 31584976

Showing the first eight; more decompositions exist.
