Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584968, here are decompositions:

7 + 31584961 = 31584968
61 + 31584907 = 31584968
67 + 31584901 = 31584968
139 + 31584829 = 31584968
199 + 31584769 = 31584968
211 + 31584757 = 31584968
271 + 31584697 = 31584968
367 + 31584601 = 31584968

Showing the first eight; more decompositions exist.
