Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548852, here are decompositions:

29 + 31548823 = 31548852
89 + 31548763 = 31548852
103 + 31548749 = 31548852
109 + 31548743 = 31548852
113 + 31548739 = 31548852
193 + 31548659 = 31548852
199 + 31548653 = 31548852
211 + 31548641 = 31548852

Showing the first eight; more decompositions exist.
