Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584776, here are decompositions:

7 + 31584769 = 31584776
19 + 31584757 = 31584776
73 + 31584703 = 31584776
79 + 31584697 = 31584776
109 + 31584667 = 31584776
163 + 31584613 = 31584776
199 + 31584577 = 31584776
229 + 31584547 = 31584776

Showing the first eight; more decompositions exist.
