Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533932, here are decompositions:

13 + 31533919 = 31533932
61 + 31533871 = 31533932
103 + 31533829 = 31533932
109 + 31533823 = 31533932
163 + 31533769 = 31533932
211 + 31533721 = 31533932
271 + 31533661 = 31533932
421 + 31533511 = 31533932

Showing the first eight; more decompositions exist.
