Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583184, here are decompositions:

13 + 31583171 = 31583184
37 + 31583147 = 31583184
47 + 31583137 = 31583184
53 + 31583131 = 31583184
97 + 31583087 = 31583184
103 + 31583081 = 31583184
137 + 31583047 = 31583184
151 + 31583033 = 31583184

Showing the first eight; more decompositions exist.
