Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599884, here are decompositions:

7 + 31599877 = 31599884
13 + 31599871 = 31599884
61 + 31599823 = 31599884
73 + 31599811 = 31599884
103 + 31599781 = 31599884
157 + 31599727 = 31599884
181 + 31599703 = 31599884
331 + 31599553 = 31599884

Showing the first eight; more decompositions exist.
