Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584608, here are decompositions:

7 + 31584601 = 31584608
31 + 31584577 = 31584608
61 + 31584547 = 31584608
67 + 31584541 = 31584608
109 + 31584499 = 31584608
127 + 31584481 = 31584608
151 + 31584457 = 31584608
271 + 31584337 = 31584608

Showing the first eight; more decompositions exist.
