Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551174, here are decompositions:

13 + 31551161 = 31551174
23 + 31551151 = 31551174
37 + 31551137 = 31551174
103 + 31551071 = 31551174
107 + 31551067 = 31551174
163 + 31551011 = 31551174
181 + 31550993 = 31551174
197 + 31550977 = 31551174

Showing the first eight; more decompositions exist.
