Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547306, here are decompositions:

3 + 31547303 = 31547306
19 + 31547287 = 31547306
97 + 31547209 = 31547306
103 + 31547203 = 31547306
163 + 31547143 = 31547306
229 + 31547077 = 31547306
337 + 31546969 = 31547306
397 + 31546909 = 31547306

Showing the first eight; more decompositions exist.
