Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482328, here are decompositions:

47 + 31482281 = 31482328
71 + 31482257 = 31482328
149 + 31482179 = 31482328
239 + 31482089 = 31482328
281 + 31482047 = 31482328
347 + 31481981 = 31482328
389 + 31481939 = 31482328
461 + 31481867 = 31482328

Showing the first eight; more decompositions exist.
