Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472946, here are decompositions:

17 + 31472929 = 31472946
19 + 31472927 = 31472946
59 + 31472887 = 31472946
67 + 31472879 = 31472946
79 + 31472867 = 31472946
97 + 31472849 = 31472946
107 + 31472839 = 31472946
139 + 31472807 = 31472946

Showing the first eight; more decompositions exist.
