Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463408, here are decompositions:

19 + 31463389 = 31463408
79 + 31463329 = 31463408
127 + 31463281 = 31463408
139 + 31463269 = 31463408
181 + 31463227 = 31463408
211 + 31463197 = 31463408
241 + 31463167 = 31463408
271 + 31463137 = 31463408

Showing the first eight; more decompositions exist.
