Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622548, here are decompositions:

11 + 31622537 = 31622548
29 + 31622519 = 31622548
179 + 31622369 = 31622548
311 + 31622237 = 31622548
359 + 31622189 = 31622548
401 + 31622147 = 31622548
467 + 31622081 = 31622548
569 + 31621979 = 31622548

Showing the first eight; more decompositions exist.
