Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471194, here are decompositions:

23 + 31471171 = 31471194
47 + 31471147 = 31471194
71 + 31471123 = 31471194
101 + 31471093 = 31471194
103 + 31471091 = 31471194
151 + 31471043 = 31471194
163 + 31471031 = 31471194
193 + 31471001 = 31471194

Showing the first eight; more decompositions exist.
