Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452732, here are decompositions:

5 + 31452727 = 31452732
11 + 31452721 = 31452732
13 + 31452719 = 31452732
83 + 31452649 = 31452732
109 + 31452623 = 31452732
149 + 31452583 = 31452732
193 + 31452539 = 31452732
211 + 31452521 = 31452732

Showing the first eight; more decompositions exist.
