Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474834, here are decompositions:

5 + 31474829 = 31474834
71 + 31474763 = 31474834
101 + 31474733 = 31474834
113 + 31474721 = 31474834
233 + 31474601 = 31474834
257 + 31474577 = 31474834
263 + 31474571 = 31474834
353 + 31474481 = 31474834

Showing the first eight; more decompositions exist.
