Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547410, here are decompositions:

53 + 31547357 = 31547410
71 + 31547339 = 31547410
107 + 31547303 = 31547410
113 + 31547297 = 31547410
149 + 31547261 = 31547410
179 + 31547231 = 31547410
233 + 31547177 = 31547410
263 + 31547147 = 31547410

Showing the first eight; more decompositions exist.
