Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473976, here are decompositions:

5 + 31473971 = 31473976
59 + 31473917 = 31473976
89 + 31473887 = 31473976
113 + 31473863 = 31473976
137 + 31473839 = 31473976
167 + 31473809 = 31473976
197 + 31473779 = 31473976
269 + 31473707 = 31473976

Showing the first eight; more decompositions exist.
