Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622288, here are decompositions:

7 + 31622281 = 31622288
31 + 31622257 = 31622288
109 + 31622179 = 31622288
157 + 31622131 = 31622288
241 + 31622047 = 31622288
307 + 31621981 = 31622288
331 + 31621957 = 31622288
409 + 31621879 = 31622288

Showing the first eight; more decompositions exist.
