Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599018, here are decompositions:

29 + 31598989 = 31599018
71 + 31598947 = 31599018
79 + 31598939 = 31599018
107 + 31598911 = 31599018
109 + 31598909 = 31599018
131 + 31598887 = 31599018
151 + 31598867 = 31599018
179 + 31598839 = 31599018

Showing the first eight; more decompositions exist.
