Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583482, here are decompositions:

5 + 31583477 = 31583482
59 + 31583423 = 31583482
131 + 31583351 = 31583482
311 + 31583171 = 31583482
401 + 31583081 = 31583482
431 + 31583051 = 31583482
449 + 31583033 = 31583482
521 + 31582961 = 31583482

Showing the first eight; more decompositions exist.
