Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473354, here are decompositions:

23 + 31473331 = 31473354
41 + 31473313 = 31473354
71 + 31473283 = 31473354
103 + 31473251 = 31473354
113 + 31473241 = 31473354
137 + 31473217 = 31473354
151 + 31473203 = 31473354
163 + 31473191 = 31473354

Showing the first eight; more decompositions exist.
