Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473118, here are decompositions:

11 + 31473107 = 31473118
41 + 31473077 = 31473118
191 + 31472927 = 31473118
227 + 31472891 = 31473118
239 + 31472879 = 31473118
251 + 31472867 = 31473118
269 + 31472849 = 31473118
311 + 31472807 = 31473118

Showing the first eight; more decompositions exist.
