Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583624, here are decompositions:

3 + 31583621 = 31583624
97 + 31583527 = 31583624
103 + 31583521 = 31583624
211 + 31583413 = 31583624
271 + 31583353 = 31583624
367 + 31583257 = 31583624
487 + 31583137 = 31583624
577 + 31583047 = 31583624

Showing the first eight; more decompositions exist.
