Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583044, here are decompositions:

11 + 31583033 = 31583044
83 + 31582961 = 31583044
107 + 31582937 = 31583044
113 + 31582931 = 31583044
131 + 31582913 = 31583044
137 + 31582907 = 31583044
197 + 31582847 = 31583044
263 + 31582781 = 31583044

Showing the first eight; more decompositions exist.
