Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474408, here are decompositions:

5 + 31474403 = 31474408
11 + 31474397 = 31474408
89 + 31474319 = 31474408
101 + 31474307 = 31474408
107 + 31474301 = 31474408
191 + 31474217 = 31474408
347 + 31474061 = 31474408
401 + 31474007 = 31474408

Showing the first eight; more decompositions exist.
