Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464406, here are decompositions:

5 + 31464401 = 31464406
47 + 31464359 = 31464406
137 + 31464269 = 31464406
173 + 31464233 = 31464406
257 + 31464149 = 31464406
263 + 31464143 = 31464406
269 + 31464137 = 31464406
359 + 31464047 = 31464406

Showing the first eight; more decompositions exist.
