Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462038, here are decompositions:

17 + 31462021 = 31462038
31 + 31462007 = 31462038
59 + 31461979 = 31462038
61 + 31461977 = 31462038
89 + 31461949 = 31462038
151 + 31461887 = 31462038
197 + 31461841 = 31462038
227 + 31461811 = 31462038

Showing the first eight; more decompositions exist.
