Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622260, here are decompositions:

3 + 31622257 = 31622260
23 + 31622237 = 31622260
53 + 31622207 = 31622260
71 + 31622189 = 31622260
107 + 31622153 = 31622260
113 + 31622147 = 31622260
179 + 31622081 = 31622260
281 + 31621979 = 31622260

Showing the first eight; more decompositions exist.
