Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464234, here are decompositions:

41 + 31464193 = 31464234
47 + 31464187 = 31464234
97 + 31464137 = 31464234
167 + 31464067 = 31464234
173 + 31464061 = 31464234
233 + 31464001 = 31464234
271 + 31463963 = 31464234
293 + 31463941 = 31464234

Showing the first eight; more decompositions exist.
