Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543182, here are decompositions:

19 + 31543163 = 31543182
79 + 31543103 = 31543182
103 + 31543079 = 31543182
113 + 31543069 = 31543182
163 + 31543019 = 31543182
173 + 31543009 = 31543182
191 + 31542991 = 31543182
211 + 31542971 = 31543182

Showing the first eight; more decompositions exist.
