Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603026, here are decompositions:

17 + 31603009 = 31603026
53 + 31602973 = 31603026
67 + 31602959 = 31603026
109 + 31602917 = 31603026
127 + 31602899 = 31603026
149 + 31602877 = 31603026
163 + 31602863 = 31603026
167 + 31602859 = 31603026

Showing the first eight; more decompositions exist.
