Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547196, here are decompositions:

19 + 31547177 = 31547196
53 + 31547143 = 31547196
67 + 31547129 = 31547196
103 + 31547093 = 31547196
157 + 31547039 = 31547196
193 + 31547003 = 31547196
199 + 31546997 = 31547196
227 + 31546969 = 31547196

Showing the first eight; more decompositions exist.
