Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522956, here are decompositions:

5 + 31522951 = 31522956
19 + 31522937 = 31522956
67 + 31522889 = 31522956
83 + 31522873 = 31522956
109 + 31522847 = 31522956
239 + 31522717 = 31522956
263 + 31522693 = 31522956
293 + 31522663 = 31522956

Showing the first eight; more decompositions exist.
