Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600002, here are decompositions:

43 + 31599959 = 31600002
61 + 31599941 = 31600002
73 + 31599929 = 31600002
89 + 31599913 = 31600002
101 + 31599901 = 31600002
131 + 31599871 = 31600002
179 + 31599823 = 31600002
191 + 31599811 = 31600002

Showing the first eight; more decompositions exist.
