Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622136, here are decompositions:

5 + 31622131 = 31622136
17 + 31622119 = 31622136
23 + 31622113 = 31622136
89 + 31622047 = 31622136
157 + 31621979 = 31622136
173 + 31621963 = 31622136
179 + 31621957 = 31622136
239 + 31621897 = 31622136

Showing the first eight; more decompositions exist.
