Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547318, here are decompositions:

31 + 31547287 = 31547318
37 + 31547281 = 31547318
109 + 31547209 = 31547318
157 + 31547161 = 31547318
241 + 31547077 = 31547318
331 + 31546987 = 31547318
337 + 31546981 = 31547318
349 + 31546969 = 31547318

Showing the first eight; more decompositions exist.
