Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464290, here are decompositions:

19 + 31464271 = 31464290
97 + 31464193 = 31464290
103 + 31464187 = 31464290
211 + 31464079 = 31464290
223 + 31464067 = 31464290
229 + 31464061 = 31464290
331 + 31463959 = 31464290
349 + 31463941 = 31464290

Showing the first eight; more decompositions exist.
