Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622184, here are decompositions:

5 + 31622179 = 31622184
17 + 31622167 = 31622184
31 + 31622153 = 31622184
37 + 31622147 = 31622184
43 + 31622141 = 31622184
53 + 31622131 = 31622184
71 + 31622113 = 31622184
103 + 31622081 = 31622184

Showing the first eight; more decompositions exist.
