Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583214, here are decompositions:

43 + 31583171 = 31583214
67 + 31583147 = 31583214
83 + 31583131 = 31583214
127 + 31583087 = 31583214
163 + 31583051 = 31583214
167 + 31583047 = 31583214
181 + 31583033 = 31583214
191 + 31583023 = 31583214

Showing the first eight; more decompositions exist.
