Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547476, here are decompositions:

5 + 31547471 = 31547476
17 + 31547459 = 31547476
137 + 31547339 = 31547476
173 + 31547303 = 31547476
179 + 31547297 = 31547476
347 + 31547129 = 31547476
383 + 31547093 = 31547476
479 + 31546997 = 31547476

Showing the first eight; more decompositions exist.
