Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599948, here are decompositions:

7 + 31599941 = 31599948
19 + 31599929 = 31599948
31 + 31599917 = 31599948
47 + 31599901 = 31599948
71 + 31599877 = 31599948
89 + 31599859 = 31599948
137 + 31599811 = 31599948
139 + 31599809 = 31599948

Showing the first eight; more decompositions exist.
