Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473038, here are decompositions:

7 + 31473031 = 31473038
109 + 31472929 = 31473038
151 + 31472887 = 31473038
199 + 31472839 = 31473038
211 + 31472827 = 31473038
601 + 31472437 = 31473038
829 + 31472209 = 31473038
859 + 31472179 = 31473038

Showing the first eight; more decompositions exist.
