Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473066, here are decompositions:

5 + 31473061 = 31473066
29 + 31473037 = 31473066
83 + 31472983 = 31473066
103 + 31472963 = 31473066
137 + 31472929 = 31473066
139 + 31472927 = 31473066
179 + 31472887 = 31473066
199 + 31472867 = 31473066

Showing the first eight; more decompositions exist.
