Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462948, here are decompositions:

17 + 31462931 = 31462948
47 + 31462901 = 31462948
59 + 31462889 = 31462948
71 + 31462877 = 31462948
137 + 31462811 = 31462948
191 + 31462757 = 31462948
197 + 31462751 = 31462948
359 + 31462589 = 31462948

Showing the first eight; more decompositions exist.
