Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482112, here are decompositions:

23 + 31482089 = 31482112
29 + 31482083 = 31482112
71 + 31482041 = 31482112
131 + 31481981 = 31482112
173 + 31481939 = 31482112
191 + 31481921 = 31482112
269 + 31481843 = 31482112
281 + 31481831 = 31482112

Showing the first eight; more decompositions exist.
