Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473564, here are decompositions:

41 + 31473523 = 31473564
107 + 31473457 = 31473564
127 + 31473437 = 31473564
151 + 31473413 = 31473564
167 + 31473397 = 31473564
233 + 31473331 = 31473564
251 + 31473313 = 31473564
281 + 31473283 = 31473564

Showing the first eight; more decompositions exist.
