Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471026, here are decompositions:

19 + 31471007 = 31471026
29 + 31470997 = 31471026
73 + 31470953 = 31471026
109 + 31470917 = 31471026
113 + 31470913 = 31471026
137 + 31470889 = 31471026
157 + 31470869 = 31471026
163 + 31470863 = 31471026

Showing the first eight; more decompositions exist.
