Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476198, here are decompositions:

11 + 31476187 = 31476198
29 + 31476169 = 31476198
41 + 31476157 = 31476198
79 + 31476119 = 31476198
101 + 31476097 = 31476198
139 + 31476059 = 31476198
167 + 31476031 = 31476198
181 + 31476017 = 31476198

Showing the first eight; more decompositions exist.
