Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518332, here are decompositions:

3 + 31518329 = 31518332
19 + 31518313 = 31518332
31 + 31518301 = 31518332
61 + 31518271 = 31518332
73 + 31518259 = 31518332
103 + 31518229 = 31518332
151 + 31518181 = 31518332
193 + 31518139 = 31518332

Showing the first eight; more decompositions exist.
