Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584764, here are decompositions:

7 + 31584757 = 31584764
61 + 31584703 = 31584764
67 + 31584697 = 31584764
97 + 31584667 = 31584764
151 + 31584613 = 31584764
157 + 31584607 = 31584764
163 + 31584601 = 31584764
223 + 31584541 = 31584764

Showing the first eight; more decompositions exist.
