Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603122, here are decompositions:

11 + 31603111 = 31603122
13 + 31603109 = 31603122
43 + 31603079 = 31603122
113 + 31603009 = 31603122
149 + 31602973 = 31603122
163 + 31602959 = 31603122
191 + 31602931 = 31603122
223 + 31602899 = 31603122

Showing the first eight; more decompositions exist.
