Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473306, here are decompositions:

23 + 31473283 = 31473306
43 + 31473263 = 31473306
89 + 31473217 = 31473306
97 + 31473209 = 31473306
103 + 31473203 = 31473306
197 + 31473109 = 31473306
199 + 31473107 = 31473306
223 + 31473083 = 31473306

Showing the first eight; more decompositions exist.
