Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474270, here are decompositions:

17 + 31474253 = 31474270
53 + 31474217 = 31474270
197 + 31474073 = 31474270
227 + 31474043 = 31474270
263 + 31474007 = 31474270
293 + 31473977 = 31474270
353 + 31473917 = 31474270
383 + 31473887 = 31474270

Showing the first eight; more decompositions exist.
