Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517016, here are decompositions:

5 + 31517011 = 31517016
23 + 31516993 = 31517016
43 + 31516973 = 31517016
127 + 31516889 = 31517016
137 + 31516879 = 31517016
197 + 31516819 = 31517016
227 + 31516789 = 31517016
229 + 31516787 = 31517016

Showing the first eight; more decompositions exist.
