Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622052, here are decompositions:

5 + 31622047 = 31622052
71 + 31621981 = 31622052
73 + 31621979 = 31622052
89 + 31621963 = 31622052
103 + 31621949 = 31622052
151 + 31621901 = 31622052
173 + 31621879 = 31622052
313 + 31621739 = 31622052

Showing the first eight; more decompositions exist.
