Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544288, here are decompositions:

7 + 31544281 = 31544288
67 + 31544221 = 31544288
109 + 31544179 = 31544288
157 + 31544131 = 31544288
199 + 31544089 = 31544288
211 + 31544077 = 31544288
277 + 31544011 = 31544288
577 + 31543711 = 31544288

Showing the first eight; more decompositions exist.
