Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482174, here are decompositions:

5 + 31482169 = 31482174
7 + 31482167 = 31482174
71 + 31482103 = 31482174
107 + 31482067 = 31482174
127 + 31482047 = 31482174
131 + 31482043 = 31482174
137 + 31482037 = 31482174
193 + 31481981 = 31482174

Showing the first eight; more decompositions exist.
