Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473298, here are decompositions:

47 + 31473251 = 31473298
89 + 31473209 = 31473298
107 + 31473191 = 31473298
137 + 31473161 = 31473298
191 + 31473107 = 31473298
257 + 31473041 = 31473298
419 + 31472879 = 31473298
431 + 31472867 = 31473298

Showing the first eight; more decompositions exist.
