Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583802, here are decompositions:

23 + 31583779 = 31583802
31 + 31583771 = 31583802
53 + 31583749 = 31583802
73 + 31583729 = 31583802
101 + 31583701 = 31583802
109 + 31583693 = 31583802
139 + 31583663 = 31583802
181 + 31583621 = 31583802

Showing the first eight; more decompositions exist.
