Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569096, here are decompositions:

5 + 31569091 = 31569096
23 + 31569073 = 31569096
37 + 31569059 = 31569096
47 + 31569049 = 31569096
59 + 31569037 = 31569096
127 + 31568969 = 31569096
157 + 31568939 = 31569096
179 + 31568917 = 31569096

Showing the first eight; more decompositions exist.
