Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472934, here are decompositions:

5 + 31472929 = 31472934
7 + 31472927 = 31472934
43 + 31472891 = 31472934
47 + 31472887 = 31472934
67 + 31472867 = 31472934
83 + 31472851 = 31472934
107 + 31472827 = 31472934
127 + 31472807 = 31472934

Showing the first eight; more decompositions exist.
