Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473216, here are decompositions:

7 + 31473209 = 31473216
13 + 31473203 = 31473216
29 + 31473187 = 31473216
43 + 31473173 = 31473216
53 + 31473163 = 31473216
107 + 31473109 = 31473216
109 + 31473107 = 31473216
139 + 31473077 = 31473216

Showing the first eight; more decompositions exist.
