Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523222, here are decompositions:

13 + 31523209 = 31523222
61 + 31523161 = 31523222
79 + 31523143 = 31523222
103 + 31523119 = 31523222
109 + 31523113 = 31523222
271 + 31522951 = 31523222
349 + 31522873 = 31523222
631 + 31522591 = 31523222

Showing the first eight; more decompositions exist.
