Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474324, here are decompositions:

5 + 31474319 = 31474324
17 + 31474307 = 31474324
23 + 31474301 = 31474324
71 + 31474253 = 31474324
107 + 31474217 = 31474324
251 + 31474073 = 31474324
263 + 31474061 = 31474324
281 + 31474043 = 31474324

Showing the first eight; more decompositions exist.
