Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463528, here are decompositions:

139 + 31463389 = 31463528
199 + 31463329 = 31463528
211 + 31463317 = 31463528
331 + 31463197 = 31463528
367 + 31463161 = 31463528
619 + 31462909 = 31463528
631 + 31462897 = 31463528
757 + 31462771 = 31463528

Showing the first eight; more decompositions exist.
