Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474338, here are decompositions:

19 + 31474319 = 31474338
31 + 31474307 = 31474338
37 + 31474301 = 31474338
47 + 31474291 = 31474338
89 + 31474249 = 31474338
167 + 31474171 = 31474338
197 + 31474141 = 31474338
227 + 31474111 = 31474338

Showing the first eight; more decompositions exist.
