Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482948, here are decompositions:

41 + 31482907 = 31482948
59 + 31482889 = 31482948
89 + 31482859 = 31482948
109 + 31482839 = 31482948
127 + 31482821 = 31482948
149 + 31482799 = 31482948
239 + 31482709 = 31482948
241 + 31482707 = 31482948

Showing the first eight; more decompositions exist.
