Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473492, here are decompositions:

5 + 31473487 = 31473492
13 + 31473479 = 31473492
79 + 31473413 = 31473492
179 + 31473313 = 31473492
229 + 31473263 = 31473492
241 + 31473251 = 31473492
251 + 31473241 = 31473492
283 + 31473209 = 31473492

Showing the first eight; more decompositions exist.
