Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476160, here are decompositions:

3 + 31476157 = 31476160
11 + 31476149 = 31476160
17 + 31476143 = 31476160
41 + 31476119 = 31476160
47 + 31476113 = 31476160
101 + 31476059 = 31476160
197 + 31475963 = 31476160
251 + 31475909 = 31476160

Showing the first eight; more decompositions exist.
