Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583548, here are decompositions:

41 + 31583507 = 31583548
71 + 31583477 = 31583548
197 + 31583351 = 31583548
389 + 31583159 = 31583548
401 + 31583147 = 31583548
461 + 31583087 = 31583548
467 + 31583081 = 31583548
587 + 31582961 = 31583548

Showing the first eight; more decompositions exist.
