Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600174, here are decompositions:

17 + 31600157 = 31600174
41 + 31600133 = 31600174
71 + 31600103 = 31600174
113 + 31600061 = 31600174
131 + 31600043 = 31600174
173 + 31600001 = 31600174
197 + 31599977 = 31600174
233 + 31599941 = 31600174

Showing the first eight; more decompositions exist.
