Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473064, here are decompositions:

3 + 31473061 = 31473064
23 + 31473041 = 31473064
101 + 31472963 = 31473064
137 + 31472927 = 31473064
173 + 31472891 = 31473064
197 + 31472867 = 31473064
251 + 31472813 = 31473064
257 + 31472807 = 31473064

Showing the first eight; more decompositions exist.
