Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482436, here are decompositions:

47 + 31482389 = 31482436
179 + 31482257 = 31482436
257 + 31482179 = 31482436
263 + 31482173 = 31482436
269 + 31482167 = 31482436
317 + 31482119 = 31482436
347 + 31482089 = 31482436
353 + 31482083 = 31482436

Showing the first eight; more decompositions exist.
