Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463708, here are decompositions:

19 + 31463689 = 31463708
181 + 31463527 = 31463708
379 + 31463329 = 31463708
439 + 31463269 = 31463708
541 + 31463167 = 31463708
547 + 31463161 = 31463708
571 + 31463137 = 31463708
631 + 31463077 = 31463708

Showing the first eight; more decompositions exist.
