Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583112, here are decompositions:

31 + 31583081 = 31583112
61 + 31583051 = 31583112
79 + 31583033 = 31583112
89 + 31583023 = 31583112
131 + 31582981 = 31583112
151 + 31582961 = 31583112
163 + 31582949 = 31583112
181 + 31582931 = 31583112

Showing the first eight; more decompositions exist.
