Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464336, here are decompositions:

67 + 31464269 = 31464336
103 + 31464233 = 31464336
149 + 31464187 = 31464336
193 + 31464143 = 31464336
199 + 31464137 = 31464336
257 + 31464079 = 31464336
269 + 31464067 = 31464336
373 + 31463963 = 31464336

Showing the first eight; more decompositions exist.
