Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462956, here are decompositions:

23 + 31462933 = 31462956
47 + 31462909 = 31462956
59 + 31462897 = 31462956
67 + 31462889 = 31462956
79 + 31462877 = 31462956
149 + 31462807 = 31462956
163 + 31462793 = 31462956
197 + 31462759 = 31462956

Showing the first eight; more decompositions exist.
