Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464384, here are decompositions:

43 + 31464341 = 31464384
103 + 31464281 = 31464384
113 + 31464271 = 31464384
151 + 31464233 = 31464384
191 + 31464193 = 31464384
197 + 31464187 = 31464384
241 + 31464143 = 31464384
317 + 31464067 = 31464384

Showing the first eight; more decompositions exist.
