Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473268, here are decompositions:

5 + 31473263 = 31473268
17 + 31473251 = 31473268
59 + 31473209 = 31473268
107 + 31473161 = 31473268
191 + 31473077 = 31473268
227 + 31473041 = 31473268
389 + 31472879 = 31473268
401 + 31472867 = 31473268

Showing the first eight; more decompositions exist.
