Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473244, here are decompositions:

3 + 31473241 = 31473244
41 + 31473203 = 31473244
53 + 31473191 = 31473244
71 + 31473173 = 31473244
83 + 31473161 = 31473244
137 + 31473107 = 31473244
167 + 31473077 = 31473244
281 + 31472963 = 31473244

Showing the first eight; more decompositions exist.
