Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583118, here are decompositions:

31 + 31583087 = 31583118
37 + 31583081 = 31583118
67 + 31583051 = 31583118
71 + 31583047 = 31583118
137 + 31582981 = 31583118
157 + 31582961 = 31583118
167 + 31582951 = 31583118
181 + 31582937 = 31583118

Showing the first eight; more decompositions exist.
