Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603022, here are decompositions:

13 + 31603009 = 31603022
163 + 31602859 = 31603022
229 + 31602793 = 31603022
331 + 31602691 = 31603022
349 + 31602673 = 31603022
433 + 31602589 = 31603022
541 + 31602481 = 31603022
571 + 31602451 = 31603022

Showing the first eight; more decompositions exist.
