Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583244, here are decompositions:

73 + 31583171 = 31583244
97 + 31583147 = 31583244
107 + 31583137 = 31583244
113 + 31583131 = 31583244
157 + 31583087 = 31583244
163 + 31583081 = 31583244
193 + 31583051 = 31583244
197 + 31583047 = 31583244

Showing the first eight; more decompositions exist.
