Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583058, here are decompositions:

7 + 31583051 = 31583058
11 + 31583047 = 31583058
97 + 31582961 = 31583058
107 + 31582951 = 31583058
109 + 31582949 = 31583058
127 + 31582931 = 31583058
151 + 31582907 = 31583058
167 + 31582891 = 31583058

Showing the first eight; more decompositions exist.
