Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547374, here are decompositions:

17 + 31547357 = 31547374
71 + 31547303 = 31547374
107 + 31547267 = 31547374
113 + 31547261 = 31547374
197 + 31547177 = 31547374
227 + 31547147 = 31547374
281 + 31547093 = 31547374
311 + 31547063 = 31547374

Showing the first eight; more decompositions exist.
