Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462984, here are decompositions:

5 + 31462979 = 31462984
53 + 31462931 = 31462984
83 + 31462901 = 31462984
107 + 31462877 = 31462984
173 + 31462811 = 31462984
191 + 31462793 = 31462984
227 + 31462757 = 31462984
233 + 31462751 = 31462984

Showing the first eight; more decompositions exist.
