Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547068, here are decompositions:

5 + 31547063 = 31547068
29 + 31547039 = 31547068
71 + 31546997 = 31547068
131 + 31546937 = 31547068
251 + 31546817 = 31547068
269 + 31546799 = 31547068
347 + 31546721 = 31547068
359 + 31546709 = 31547068

Showing the first eight; more decompositions exist.
