Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473050, here are decompositions:

13 + 31473037 = 31473050
19 + 31473031 = 31473050
67 + 31472983 = 31473050
163 + 31472887 = 31473050
199 + 31472851 = 31473050
211 + 31472839 = 31473050
223 + 31472827 = 31473050
277 + 31472773 = 31473050

Showing the first eight; more decompositions exist.
