Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468176, here are decompositions:

7 + 31468169 = 31468176
17 + 31468159 = 31468176
29 + 31468147 = 31468176
79 + 31468097 = 31468176
109 + 31468067 = 31468176
149 + 31468027 = 31468176
163 + 31468013 = 31468176
193 + 31467983 = 31468176

Showing the first eight; more decompositions exist.
