Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474876, here are decompositions:

3 + 31474873 = 31474876
47 + 31474829 = 31474876
113 + 31474763 = 31474876
317 + 31474559 = 31474876
443 + 31474433 = 31474876
479 + 31474397 = 31474876
557 + 31474319 = 31474876
569 + 31474307 = 31474876

Showing the first eight; more decompositions exist.
