Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483018, here are decompositions:

41 + 31482977 = 31483018
71 + 31482947 = 31483018
179 + 31482839 = 31483018
197 + 31482821 = 31483018
239 + 31482779 = 31483018
257 + 31482761 = 31483018
311 + 31482707 = 31483018
401 + 31482617 = 31483018

Showing the first eight; more decompositions exist.
