Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473168, here are decompositions:

5 + 31473163 = 31473168
7 + 31473161 = 31473168
17 + 31473151 = 31473168
59 + 31473109 = 31473168
61 + 31473107 = 31473168
101 + 31473067 = 31473168
107 + 31473061 = 31473168
127 + 31473041 = 31473168

Showing the first eight; more decompositions exist.
