Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600074, here are decompositions:

13 + 31600061 = 31600074
17 + 31600057 = 31600074
31 + 31600043 = 31600074
73 + 31600001 = 31600074
97 + 31599977 = 31600074
157 + 31599917 = 31600074
173 + 31599901 = 31600074
197 + 31599877 = 31600074

Showing the first eight; more decompositions exist.
