Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522622, here are decompositions:

31 + 31522591 = 31522622
73 + 31522549 = 31522622
163 + 31522459 = 31522622
181 + 31522441 = 31522622
211 + 31522411 = 31522622
283 + 31522339 = 31522622
379 + 31522243 = 31522622
601 + 31522021 = 31522622

Showing the first eight; more decompositions exist.
