Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583028, here are decompositions:

5 + 31583023 = 31583028
47 + 31582981 = 31583028
67 + 31582961 = 31583028
79 + 31582949 = 31583028
97 + 31582931 = 31583028
131 + 31582897 = 31583028
137 + 31582891 = 31583028
181 + 31582847 = 31583028

Showing the first eight; more decompositions exist.
