Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522062, here are decompositions:

41 + 31522021 = 31522062
43 + 31522019 = 31522062
71 + 31521991 = 31522062
83 + 31521979 = 31522062
109 + 31521953 = 31522062
179 + 31521883 = 31522062
199 + 31521863 = 31522062
211 + 31521851 = 31522062

Showing the first eight; more decompositions exist.
