Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473484, here are decompositions:

5 + 31473479 = 31473484
47 + 31473437 = 31473484
71 + 31473413 = 31473484
233 + 31473251 = 31473484
281 + 31473203 = 31473484
293 + 31473191 = 31473484
311 + 31473173 = 31473484
401 + 31473083 = 31473484

Showing the first eight; more decompositions exist.
