Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533852, here are decompositions:

5 + 31533847 = 31533852
13 + 31533839 = 31533852
19 + 31533833 = 31533852
23 + 31533829 = 31533852
29 + 31533823 = 31533852
61 + 31533791 = 31533852
79 + 31533773 = 31533852
83 + 31533769 = 31533852

Showing the first eight; more decompositions exist.
