Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482352, here are decompositions:

3 + 31482349 = 31482352
59 + 31482293 = 31482352
71 + 31482281 = 31482352
173 + 31482179 = 31482352
179 + 31482173 = 31482352
233 + 31482119 = 31482352
263 + 31482089 = 31482352
269 + 31482083 = 31482352

Showing the first eight; more decompositions exist.
