Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569766, here are decompositions:

3 + 31569763 = 31569766
5 + 31569761 = 31569766
29 + 31569737 = 31569766
149 + 31569617 = 31569766
167 + 31569599 = 31569766
197 + 31569569 = 31569766
317 + 31569449 = 31569766
419 + 31569347 = 31569766

Showing the first eight; more decompositions exist.
