Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474284, here are decompositions:

31 + 31474253 = 31474284
67 + 31474217 = 31474284
71 + 31474213 = 31474284
113 + 31474171 = 31474284
173 + 31474111 = 31474284
211 + 31474073 = 31474284
223 + 31474061 = 31474284
227 + 31474057 = 31474284

Showing the first eight; more decompositions exist.
