Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482256, here are decompositions:

83 + 31482173 = 31482256
89 + 31482167 = 31482256
137 + 31482119 = 31482256
167 + 31482089 = 31482256
173 + 31482083 = 31482256
317 + 31481939 = 31482256
389 + 31481867 = 31482256
419 + 31481837 = 31482256

Showing the first eight; more decompositions exist.
