Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547386, here are decompositions:

29 + 31547357 = 31547386
47 + 31547339 = 31547386
83 + 31547303 = 31547386
89 + 31547297 = 31547386
239 + 31547147 = 31547386
257 + 31547129 = 31547386
293 + 31547093 = 31547386
347 + 31547039 = 31547386

Showing the first eight; more decompositions exist.
