Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584996, here are decompositions:

29 + 31584967 = 31584996
43 + 31584953 = 31584996
89 + 31584907 = 31584996
109 + 31584887 = 31584996
127 + 31584869 = 31584996
167 + 31584829 = 31584996
173 + 31584823 = 31584996
199 + 31584797 = 31584996

Showing the first eight; more decompositions exist.
