Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473934, here are decompositions:

3 + 31473931 = 31473934
17 + 31473917 = 31473934
47 + 31473887 = 31473934
71 + 31473863 = 31473934
227 + 31473707 = 31473934
353 + 31473581 = 31473934
521 + 31473413 = 31473934
683 + 31473251 = 31473934

Showing the first eight; more decompositions exist.
