Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600010, here are decompositions:

97 + 31599913 = 31600010
109 + 31599901 = 31600010
139 + 31599871 = 31600010
151 + 31599859 = 31600010
199 + 31599811 = 31600010
229 + 31599781 = 31600010
283 + 31599727 = 31600010
307 + 31599703 = 31600010

Showing the first eight; more decompositions exist.
