Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522746, here are decompositions:

29 + 31522717 = 31522746
53 + 31522693 = 31522746
83 + 31522663 = 31522746
89 + 31522657 = 31522746
113 + 31522633 = 31522746
149 + 31522597 = 31522746
163 + 31522583 = 31522746
193 + 31522553 = 31522746

Showing the first eight; more decompositions exist.
