Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583876, here are decompositions:

13 + 31583863 = 31583876
19 + 31583857 = 31583876
67 + 31583809 = 31583876
73 + 31583803 = 31583876
97 + 31583779 = 31583876
127 + 31583749 = 31583876
349 + 31583527 = 31583876
367 + 31583509 = 31583876

Showing the first eight; more decompositions exist.
