Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584826, here are decompositions:

3 + 31584823 = 31584826
17 + 31584809 = 31584826
29 + 31584797 = 31584826
113 + 31584713 = 31584826
137 + 31584689 = 31584826
173 + 31584653 = 31584826
419 + 31584407 = 31584826
443 + 31584383 = 31584826

Showing the first eight; more decompositions exist.
