Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583892, here are decompositions:

29 + 31583863 = 31583892
61 + 31583831 = 31583892
73 + 31583819 = 31583892
83 + 31583809 = 31583892
89 + 31583803 = 31583892
113 + 31583779 = 31583892
139 + 31583753 = 31583892
163 + 31583729 = 31583892

Showing the first eight; more decompositions exist.
