Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547108, here are decompositions:

7 + 31547101 = 31547108
31 + 31547077 = 31547108
127 + 31546981 = 31547108
139 + 31546969 = 31547108
199 + 31546909 = 31547108
277 + 31546831 = 31547108
349 + 31546759 = 31547108
367 + 31546741 = 31547108

Showing the first eight; more decompositions exist.
