Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473214, here are decompositions:

5 + 31473209 = 31473214
11 + 31473203 = 31473214
23 + 31473191 = 31473214
41 + 31473173 = 31473214
53 + 31473161 = 31473214
107 + 31473107 = 31473214
131 + 31473083 = 31473214
137 + 31473077 = 31473214

Showing the first eight; more decompositions exist.
