Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622236, here are decompositions:

29 + 31622207 = 31622236
47 + 31622189 = 31622236
53 + 31622183 = 31622236
83 + 31622153 = 31622236
89 + 31622147 = 31622236
257 + 31621979 = 31622236
389 + 31621847 = 31622236
557 + 31621679 = 31622236

Showing the first eight; more decompositions exist.
