Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518096, here are decompositions:

7 + 31518089 = 31518096
47 + 31518049 = 31518096
59 + 31518037 = 31518096
73 + 31518023 = 31518096
89 + 31518007 = 31518096
97 + 31517999 = 31518096
347 + 31517749 = 31518096
367 + 31517729 = 31518096

Showing the first eight; more decompositions exist.
