Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517022, here are decompositions:

11 + 31517011 = 31517022
29 + 31516993 = 31517022
41 + 31516981 = 31517022
71 + 31516951 = 31517022
181 + 31516841 = 31517022
211 + 31516811 = 31517022
233 + 31516789 = 31517022
241 + 31516781 = 31517022

Showing the first eight; more decompositions exist.
