Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518092, here are decompositions:

3 + 31518089 = 31518092
31 + 31518061 = 31518092
43 + 31518049 = 31518092
61 + 31518031 = 31518092
139 + 31517953 = 31518092
181 + 31517911 = 31518092
241 + 31517851 = 31518092
439 + 31517653 = 31518092

Showing the first eight; more decompositions exist.
