Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482538, here are decompositions:

29 + 31482509 = 31482538
137 + 31482401 = 31482538
149 + 31482389 = 31482538
257 + 31482281 = 31482538
281 + 31482257 = 31482538
359 + 31482179 = 31482538
419 + 31482119 = 31482538
449 + 31482089 = 31482538

Showing the first eight; more decompositions exist.
