Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584982, here are decompositions:

29 + 31584953 = 31584982
101 + 31584881 = 31584982
113 + 31584869 = 31584982
173 + 31584809 = 31584982
269 + 31584713 = 31584982
293 + 31584689 = 31584982
431 + 31584551 = 31584982
593 + 31584389 = 31584982

Showing the first eight; more decompositions exist.
