Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600030, here are decompositions:

29 + 31600001 = 31600030
53 + 31599977 = 31600030
71 + 31599959 = 31600030
89 + 31599941 = 31600030
101 + 31599929 = 31600030
113 + 31599917 = 31600030
257 + 31599773 = 31600030
263 + 31599767 = 31600030

Showing the first eight; more decompositions exist.
