Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473312, here are decompositions:

29 + 31473283 = 31473312
61 + 31473251 = 31473312
71 + 31473241 = 31473312
103 + 31473209 = 31473312
109 + 31473203 = 31473312
139 + 31473173 = 31473312
149 + 31473163 = 31473312
151 + 31473161 = 31473312

Showing the first eight; more decompositions exist.
