Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482232, here are decompositions:

3 + 31482229 = 31482232
53 + 31482179 = 31482232
59 + 31482173 = 31482232
113 + 31482119 = 31482232
149 + 31482083 = 31482232
191 + 31482041 = 31482232
251 + 31481981 = 31482232
281 + 31481951 = 31482232

Showing the first eight; more decompositions exist.
