Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473474, here are decompositions:

17 + 31473457 = 31473474
37 + 31473437 = 31473474
61 + 31473413 = 31473474
191 + 31473283 = 31473474
211 + 31473263 = 31473474
223 + 31473251 = 31473474
233 + 31473241 = 31473474
257 + 31473217 = 31473474

Showing the first eight; more decompositions exist.
