Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464258, here are decompositions:

71 + 31464187 = 31464258
109 + 31464149 = 31464258
179 + 31464079 = 31464258
191 + 31464067 = 31464258
197 + 31464061 = 31464258
211 + 31464047 = 31464258
227 + 31464031 = 31464258
257 + 31464001 = 31464258

Showing the first eight; more decompositions exist.
