Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482250, here are decompositions:

3 + 31482247 = 31482250
71 + 31482179 = 31482250
83 + 31482167 = 31482250
131 + 31482119 = 31482250
167 + 31482083 = 31482250
269 + 31481981 = 31482250
311 + 31481939 = 31482250
383 + 31481867 = 31482250

Showing the first eight; more decompositions exist.
