Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473948, here are decompositions:

17 + 31473931 = 31473948
31 + 31473917 = 31473948
41 + 31473907 = 31473948
47 + 31473901 = 31473948
61 + 31473887 = 31473948
101 + 31473847 = 31473948
109 + 31473839 = 31473948
137 + 31473811 = 31473948

Showing the first eight; more decompositions exist.
