Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588574, here are decompositions:

13 + 31588561 = 31588574
103 + 31588471 = 31588574
223 + 31588351 = 31588574
271 + 31588303 = 31588574
307 + 31588267 = 31588574
373 + 31588201 = 31588574
487 + 31588087 = 31588574
571 + 31588003 = 31588574

Showing the first eight; more decompositions exist.
