Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584026, here are decompositions:

7 + 31584019 = 31584026
37 + 31583989 = 31584026
43 + 31583983 = 31584026
163 + 31583863 = 31584026
223 + 31583803 = 31584026
277 + 31583749 = 31584026
367 + 31583659 = 31584026
499 + 31583527 = 31584026

Showing the first eight; more decompositions exist.
