Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473160, here are decompositions:

53 + 31473107 = 31473160
83 + 31473077 = 31473160
197 + 31472963 = 31473160
233 + 31472927 = 31473160
269 + 31472891 = 31473160
281 + 31472879 = 31473160
293 + 31472867 = 31473160
311 + 31472849 = 31473160

Showing the first eight; more decompositions exist.
