Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462944, here are decompositions:

11 + 31462933 = 31462944
13 + 31462931 = 31462944
43 + 31462901 = 31462944
47 + 31462897 = 31462944
67 + 31462877 = 31462944
113 + 31462831 = 31462944
137 + 31462807 = 31462944
151 + 31462793 = 31462944

Showing the first eight; more decompositions exist.
