Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584846, here are decompositions:

17 + 31584829 = 31584846
23 + 31584823 = 31584846
37 + 31584809 = 31584846
89 + 31584757 = 31584846
149 + 31584697 = 31584846
157 + 31584689 = 31584846
179 + 31584667 = 31584846
193 + 31584653 = 31584846

Showing the first eight; more decompositions exist.
