Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583526, here are decompositions:

5 + 31583521 = 31583526
17 + 31583509 = 31583526
19 + 31583507 = 31583526
89 + 31583437 = 31583526
103 + 31583423 = 31583526
113 + 31583413 = 31583526
173 + 31583353 = 31583526
257 + 31583269 = 31583526

Showing the first eight; more decompositions exist.
