Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583976, here are decompositions:

5 + 31583971 = 31583976
79 + 31583897 = 31583976
113 + 31583863 = 31583976
139 + 31583837 = 31583976
157 + 31583819 = 31583976
167 + 31583809 = 31583976
173 + 31583803 = 31583976
197 + 31583779 = 31583976

Showing the first eight; more decompositions exist.
