Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482358, here are decompositions:

101 + 31482257 = 31482358
179 + 31482179 = 31482358
191 + 31482167 = 31482358
239 + 31482119 = 31482358
269 + 31482089 = 31482358
311 + 31482047 = 31482358
317 + 31482041 = 31482358
419 + 31481939 = 31482358

Showing the first eight; more decompositions exist.
