Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592976, here are decompositions:

5 + 31592971 = 31592976
17 + 31592959 = 31592976
29 + 31592947 = 31592976
53 + 31592923 = 31592976
127 + 31592849 = 31592976
167 + 31592809 = 31592976
179 + 31592797 = 31592976
197 + 31592779 = 31592976

Showing the first eight; more decompositions exist.
