Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482238, here are decompositions:

59 + 31482179 = 31482238
71 + 31482167 = 31482238
149 + 31482089 = 31482238
191 + 31482047 = 31482238
197 + 31482041 = 31482238
257 + 31481981 = 31482238
317 + 31481921 = 31482238
401 + 31481837 = 31482238

Showing the first eight; more decompositions exist.
