Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569852, here are decompositions:

23 + 31569829 = 31569852
59 + 31569793 = 31569852
71 + 31569781 = 31569852
89 + 31569763 = 31569852
101 + 31569751 = 31569852
151 + 31569701 = 31569852
163 + 31569689 = 31569852
211 + 31569641 = 31569852

Showing the first eight; more decompositions exist.
