Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474266, here are decompositions:

13 + 31474253 = 31474266
17 + 31474249 = 31474266
53 + 31474213 = 31474266
137 + 31474129 = 31474266
193 + 31474073 = 31474266
223 + 31474043 = 31474266
233 + 31474033 = 31474266
349 + 31473917 = 31474266

Showing the first eight; more decompositions exist.
