Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547058, here are decompositions:

19 + 31547039 = 31547058
61 + 31546997 = 31547058
71 + 31546987 = 31547058
89 + 31546969 = 31547058
149 + 31546909 = 31547058
167 + 31546891 = 31547058
197 + 31546861 = 31547058
211 + 31546847 = 31547058

Showing the first eight; more decompositions exist.
