Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473522, here are decompositions:

43 + 31473479 = 31473522
109 + 31473413 = 31473522
163 + 31473359 = 31473522
191 + 31473331 = 31473522
239 + 31473283 = 31473522
271 + 31473251 = 31473522
281 + 31473241 = 31473522
313 + 31473209 = 31473522

Showing the first eight; more decompositions exist.
