Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464274, here are decompositions:

3 + 31464271 = 31464274
5 + 31464269 = 31464274
41 + 31464233 = 31464274
131 + 31464143 = 31464274
137 + 31464137 = 31464274
227 + 31464047 = 31464274
311 + 31463963 = 31464274
353 + 31463921 = 31464274

Showing the first eight; more decompositions exist.
