Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463306, here are decompositions:

37 + 31463269 = 31463306
79 + 31463227 = 31463306
103 + 31463203 = 31463306
109 + 31463197 = 31463306
139 + 31463167 = 31463306
223 + 31463083 = 31463306
229 + 31463077 = 31463306
283 + 31463023 = 31463306

Showing the first eight; more decompositions exist.
