Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569024, here are decompositions:

103 + 31568921 = 31569024
107 + 31568917 = 31569024
127 + 31568897 = 31569024
173 + 31568851 = 31569024
181 + 31568843 = 31569024
191 + 31568833 = 31569024
197 + 31568827 = 31569024
257 + 31568767 = 31569024

Showing the first eight; more decompositions exist.
