Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482790, here are decompositions:

11 + 31482779 = 31482790
29 + 31482761 = 31482790
47 + 31482743 = 31482790
83 + 31482707 = 31482790
107 + 31482683 = 31482790
149 + 31482641 = 31482790
173 + 31482617 = 31482790
191 + 31482599 = 31482790

Showing the first eight; more decompositions exist.
