Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474234, here are decompositions:

17 + 31474217 = 31474234
173 + 31474061 = 31474234
191 + 31474043 = 31474234
227 + 31474007 = 31474234
257 + 31473977 = 31474234
263 + 31473971 = 31474234
317 + 31473917 = 31474234
347 + 31473887 = 31474234

Showing the first eight; more decompositions exist.
