Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473078, here are decompositions:

11 + 31473067 = 31473078
17 + 31473061 = 31473078
37 + 31473041 = 31473078
41 + 31473037 = 31473078
47 + 31473031 = 31473078
149 + 31472929 = 31473078
151 + 31472927 = 31473078
191 + 31472887 = 31473078

Showing the first eight; more decompositions exist.
