Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583488, here are decompositions:

11 + 31583477 = 31583488
137 + 31583351 = 31583488
317 + 31583171 = 31583488
401 + 31583087 = 31583488
557 + 31582931 = 31583488
641 + 31582847 = 31583488
809 + 31582679 = 31583488
821 + 31582667 = 31583488

Showing the first eight; more decompositions exist.
