Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583564, here are decompositions:

3 + 31583561 = 31583564
37 + 31583527 = 31583564
43 + 31583521 = 31583564
127 + 31583437 = 31583564
151 + 31583413 = 31583564
211 + 31583353 = 31583564
241 + 31583323 = 31583564
283 + 31583281 = 31583564

Showing the first eight; more decompositions exist.
