Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583274, here are decompositions:

5 + 31583269 = 31583274
17 + 31583257 = 31583274
103 + 31583171 = 31583274
127 + 31583147 = 31583274
137 + 31583137 = 31583274
193 + 31583081 = 31583274
223 + 31583051 = 31583274
227 + 31583047 = 31583274

Showing the first eight; more decompositions exist.
