Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603948, here are decompositions:

17 + 31603931 = 31603948
29 + 31603919 = 31603948
59 + 31603889 = 31603948
71 + 31603877 = 31603948
191 + 31603757 = 31603948
197 + 31603751 = 31603948
227 + 31603721 = 31603948
239 + 31603709 = 31603948

Showing the first eight; more decompositions exist.
