Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622544, here are decompositions:

7 + 31622537 = 31622544
53 + 31622491 = 31622544
71 + 31622473 = 31622544
167 + 31622377 = 31622544
197 + 31622347 = 31622544
251 + 31622293 = 31622544
257 + 31622287 = 31622544
263 + 31622281 = 31622544

Showing the first eight; more decompositions exist.
