Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473448, here are decompositions:

11 + 31473437 = 31473448
89 + 31473359 = 31473448
197 + 31473251 = 31473448
239 + 31473209 = 31473448
257 + 31473191 = 31473448
521 + 31472927 = 31473448
557 + 31472891 = 31473448
569 + 31472879 = 31473448

Showing the first eight; more decompositions exist.
