Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533982, here are decompositions:

3 + 31533979 = 31533982
23 + 31533959 = 31533982
59 + 31533923 = 31533982
71 + 31533911 = 31533982
149 + 31533833 = 31533982
191 + 31533791 = 31533982
383 + 31533599 = 31533982
401 + 31533581 = 31533982

Showing the first eight; more decompositions exist.
