Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518014, here are decompositions:

7 + 31518007 = 31518014
13 + 31518001 = 31518014
61 + 31517953 = 31518014
103 + 31517911 = 31518014
127 + 31517887 = 31518014
163 + 31517851 = 31518014
313 + 31517701 = 31518014
373 + 31517641 = 31518014

Showing the first eight; more decompositions exist.
