Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464270, here are decompositions:

37 + 31464233 = 31464270
83 + 31464187 = 31464270
127 + 31464143 = 31464270
191 + 31464079 = 31464270
223 + 31464047 = 31464270
239 + 31464031 = 31464270
269 + 31464001 = 31464270
307 + 31463963 = 31464270

Showing the first eight; more decompositions exist.
