Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474576, here are decompositions:

5 + 31474571 = 31474576
17 + 31474559 = 31474576
173 + 31474403 = 31474576
179 + 31474397 = 31474576
233 + 31474343 = 31474576
257 + 31474319 = 31474576
269 + 31474307 = 31474576
359 + 31474217 = 31474576

Showing the first eight; more decompositions exist.
