Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547308, here are decompositions:

5 + 31547303 = 31547308
11 + 31547297 = 31547308
41 + 31547267 = 31547308
47 + 31547261 = 31547308
131 + 31547177 = 31547308
179 + 31547129 = 31547308
269 + 31547039 = 31547308
311 + 31546997 = 31547308

Showing the first eight; more decompositions exist.
