Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518362, here are decompositions:

19 + 31518343 = 31518362
61 + 31518301 = 31518362
103 + 31518259 = 31518362
181 + 31518181 = 31518362
199 + 31518163 = 31518362
223 + 31518139 = 31518362
313 + 31518049 = 31518362
331 + 31518031 = 31518362

Showing the first eight; more decompositions exist.
