Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544568, here are decompositions:

7 + 31544561 = 31544568
17 + 31544551 = 31544568
37 + 31544531 = 31544568
59 + 31544509 = 31544568
151 + 31544417 = 31544568
197 + 31544371 = 31544568
257 + 31544311 = 31544568
271 + 31544297 = 31544568

Showing the first eight; more decompositions exist.
