Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584052, here are decompositions:

53 + 31583999 = 31584052
131 + 31583921 = 31584052
233 + 31583819 = 31584052
281 + 31583771 = 31584052
359 + 31583693 = 31584052
389 + 31583663 = 31584052
419 + 31583633 = 31584052
431 + 31583621 = 31584052

Showing the first eight; more decompositions exist.
