Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473054, here are decompositions:

13 + 31473041 = 31473054
17 + 31473037 = 31473054
23 + 31473031 = 31473054
71 + 31472983 = 31473054
127 + 31472927 = 31473054
163 + 31472891 = 31473054
167 + 31472887 = 31473054
227 + 31472827 = 31473054

Showing the first eight; more decompositions exist.
