Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473462, here are decompositions:

5 + 31473457 = 31473462
103 + 31473359 = 31473462
131 + 31473331 = 31473462
149 + 31473313 = 31473462
179 + 31473283 = 31473462
199 + 31473263 = 31473462
211 + 31473251 = 31473462
271 + 31473191 = 31473462

Showing the first eight; more decompositions exist.
