Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518302, here are decompositions:

31 + 31518271 = 31518302
43 + 31518259 = 31518302
73 + 31518229 = 31518302
139 + 31518163 = 31518302
163 + 31518139 = 31518302
241 + 31518061 = 31518302
271 + 31518031 = 31518302
349 + 31517953 = 31518302

Showing the first eight; more decompositions exist.
