Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482458, here are decompositions:

19 + 31482439 = 31482458
31 + 31482427 = 31482458
109 + 31482349 = 31482458
151 + 31482307 = 31482458
181 + 31482277 = 31482458
211 + 31482247 = 31482458
229 + 31482229 = 31482458
421 + 31482037 = 31482458

Showing the first eight; more decompositions exist.
