Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473124, here are decompositions:

17 + 31473107 = 31473124
41 + 31473083 = 31473124
47 + 31473077 = 31473124
83 + 31473041 = 31473124
197 + 31472927 = 31473124
233 + 31472891 = 31473124
257 + 31472867 = 31473124
311 + 31472813 = 31473124

Showing the first eight; more decompositions exist.
