Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533936, here are decompositions:

13 + 31533923 = 31533936
17 + 31533919 = 31533936
89 + 31533847 = 31533936
97 + 31533839 = 31533936
103 + 31533833 = 31533936
107 + 31533829 = 31533936
113 + 31533823 = 31533936
163 + 31533773 = 31533936

Showing the first eight; more decompositions exist.
