Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522828, here are decompositions:

5 + 31522823 = 31522828
587 + 31522241 = 31522828
599 + 31522229 = 31522828
647 + 31522181 = 31522828
809 + 31522019 = 31522828
941 + 31521887 = 31522828
977 + 31521851 = 31522828
1181 + 31521647 = 31522828

Showing the first eight; more decompositions exist.
