Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462938, here are decompositions:

5 + 31462933 = 31462938
7 + 31462931 = 31462938
29 + 31462909 = 31462938
37 + 31462901 = 31462938
41 + 31462897 = 31462938
61 + 31462877 = 31462938
107 + 31462831 = 31462938
127 + 31462811 = 31462938

Showing the first eight; more decompositions exist.
