Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482468, here are decompositions:

29 + 31482439 = 31482468
41 + 31482427 = 31482468
67 + 31482401 = 31482468
79 + 31482389 = 31482468
131 + 31482337 = 31482468
191 + 31482277 = 31482468
197 + 31482271 = 31482468
211 + 31482257 = 31482468

Showing the first eight; more decompositions exist.
