Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468182, here are decompositions:

13 + 31468169 = 31468182
23 + 31468159 = 31468182
181 + 31468001 = 31468182
199 + 31467983 = 31468182
233 + 31467949 = 31468182
271 + 31467911 = 31468182
283 + 31467899 = 31468182
353 + 31467829 = 31468182

Showing the first eight; more decompositions exist.
