Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547384, here are decompositions:

67 + 31547317 = 31547384
97 + 31547287 = 31547384
103 + 31547281 = 31547384
181 + 31547203 = 31547384
223 + 31547161 = 31547384
241 + 31547143 = 31547384
283 + 31547101 = 31547384
307 + 31547077 = 31547384

Showing the first eight; more decompositions exist.
