Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464252, here are decompositions:

19 + 31464233 = 31464252
59 + 31464193 = 31464252
103 + 31464149 = 31464252
109 + 31464143 = 31464252
173 + 31464079 = 31464252
191 + 31464061 = 31464252
251 + 31464001 = 31464252
293 + 31463959 = 31464252

Showing the first eight; more decompositions exist.
