Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547016, here are decompositions:

13 + 31547003 = 31547016
19 + 31546997 = 31547016
29 + 31546987 = 31547016
47 + 31546969 = 31547016
79 + 31546937 = 31547016
103 + 31546913 = 31547016
107 + 31546909 = 31547016
173 + 31546843 = 31547016

Showing the first eight; more decompositions exist.
