Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547106, here are decompositions:

5 + 31547101 = 31547106
13 + 31547093 = 31547106
29 + 31547077 = 31547106
43 + 31547063 = 31547106
67 + 31547039 = 31547106
103 + 31547003 = 31547106
109 + 31546997 = 31547106
137 + 31546969 = 31547106

Showing the first eight; more decompositions exist.
