Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547198, here are decompositions:

37 + 31547161 = 31547198
97 + 31547101 = 31547198
211 + 31546987 = 31547198
229 + 31546969 = 31547198
307 + 31546891 = 31547198
337 + 31546861 = 31547198
367 + 31546831 = 31547198
409 + 31546789 = 31547198

Showing the first eight; more decompositions exist.
