Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463882, here are decompositions:

3 + 31463879 = 31463882
103 + 31463779 = 31463882
139 + 31463743 = 31463882
193 + 31463689 = 31463882
349 + 31463533 = 31463882
601 + 31463281 = 31463882
613 + 31463269 = 31463882
859 + 31463023 = 31463882

Showing the first eight; more decompositions exist.
