Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600180, here are decompositions:

23 + 31600157 = 31600180
47 + 31600133 = 31600180
137 + 31600043 = 31600180
179 + 31600001 = 31600180
239 + 31599941 = 31600180
251 + 31599929 = 31600180
263 + 31599917 = 31600180
419 + 31599761 = 31600180

Showing the first eight; more decompositions exist.
