Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462914, here are decompositions:

5 + 31462909 = 31462914
13 + 31462901 = 31462914
17 + 31462897 = 31462914
37 + 31462877 = 31462914
83 + 31462831 = 31462914
103 + 31462811 = 31462914
107 + 31462807 = 31462914
157 + 31462757 = 31462914

Showing the first eight; more decompositions exist.
