Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622076, here are decompositions:

29 + 31622047 = 31622076
97 + 31621979 = 31622076
113 + 31621963 = 31622076
127 + 31621949 = 31622076
179 + 31621897 = 31622076
197 + 31621879 = 31622076
229 + 31621847 = 31622076
337 + 31621739 = 31622076

Showing the first eight; more decompositions exist.
