Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473454, here are decompositions:

17 + 31473437 = 31473454
41 + 31473413 = 31473454
191 + 31473263 = 31473454
251 + 31473203 = 31473454
263 + 31473191 = 31473454
281 + 31473173 = 31473454
293 + 31473161 = 31473454
347 + 31473107 = 31473454

Showing the first eight; more decompositions exist.
