Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599882, here are decompositions:

5 + 31599877 = 31599882
11 + 31599871 = 31599882
23 + 31599859 = 31599882
59 + 31599823 = 31599882
71 + 31599811 = 31599882
73 + 31599809 = 31599882
101 + 31599781 = 31599882
109 + 31599773 = 31599882

Showing the first eight; more decompositions exist.
