Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518074, here are decompositions:

13 + 31518061 = 31518074
37 + 31518037 = 31518074
43 + 31518031 = 31518074
67 + 31518007 = 31518074
73 + 31518001 = 31518074
163 + 31517911 = 31518074
223 + 31517851 = 31518074
373 + 31517701 = 31518074

Showing the first eight; more decompositions exist.
