Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473164, here are decompositions:

3 + 31473161 = 31473164
13 + 31473151 = 31473164
97 + 31473067 = 31473164
103 + 31473061 = 31473164
127 + 31473037 = 31473164
181 + 31472983 = 31473164
277 + 31472887 = 31473164
313 + 31472851 = 31473164

Showing the first eight; more decompositions exist.
