Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505622, here are decompositions:

13 + 31505609 = 31505622
23 + 31505599 = 31505622
53 + 31505569 = 31505622
89 + 31505533 = 31505622
101 + 31505521 = 31505622
103 + 31505519 = 31505622
149 + 31505473 = 31505622
163 + 31505459 = 31505622

Showing the first eight; more decompositions exist.
