Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584946, here are decompositions:

59 + 31584887 = 31584946
137 + 31584809 = 31584946
149 + 31584797 = 31584946
233 + 31584713 = 31584946
257 + 31584689 = 31584946
293 + 31584653 = 31584946
557 + 31584389 = 31584946
563 + 31584383 = 31584946

Showing the first eight; more decompositions exist.
