Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584884, here are decompositions:

3 + 31584881 = 31584884
31 + 31584853 = 31584884
61 + 31584823 = 31584884
127 + 31584757 = 31584884
181 + 31584703 = 31584884
271 + 31584613 = 31584884
277 + 31584607 = 31584884
283 + 31584601 = 31584884

Showing the first eight; more decompositions exist.
