Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599876, here are decompositions:

5 + 31599871 = 31599876
17 + 31599859 = 31599876
53 + 31599823 = 31599876
67 + 31599809 = 31599876
103 + 31599773 = 31599876
109 + 31599767 = 31599876
149 + 31599727 = 31599876
173 + 31599703 = 31599876

Showing the first eight; more decompositions exist.
