Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518104, here are decompositions:

43 + 31518061 = 31518104
67 + 31518037 = 31518104
73 + 31518031 = 31518104
97 + 31518007 = 31518104
103 + 31518001 = 31518104
151 + 31517953 = 31518104
193 + 31517911 = 31518104
463 + 31517641 = 31518104

Showing the first eight; more decompositions exist.
