Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473864, here are decompositions:

17 + 31473847 = 31473864
53 + 31473811 = 31473864
83 + 31473781 = 31473864
131 + 31473733 = 31473864
157 + 31473707 = 31473864
271 + 31473593 = 31473864
281 + 31473583 = 31473864
283 + 31473581 = 31473864

Showing the first eight; more decompositions exist.
