Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482976, here are decompositions:

3 + 31482973 = 31482976
29 + 31482947 = 31482976
137 + 31482839 = 31482976
197 + 31482779 = 31482976
233 + 31482743 = 31482976
269 + 31482707 = 31482976
293 + 31482683 = 31482976
359 + 31482617 = 31482976

Showing the first eight; more decompositions exist.
