Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474356, here are decompositions:

5 + 31474351 = 31474356
13 + 31474343 = 31474356
37 + 31474319 = 31474356
103 + 31474253 = 31474356
107 + 31474249 = 31474356
139 + 31474217 = 31474356
227 + 31474129 = 31474356
283 + 31474073 = 31474356

Showing the first eight; more decompositions exist.
