Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463802, here are decompositions:

5 + 31463797 = 31463802
23 + 31463779 = 31463802
43 + 31463759 = 31463802
59 + 31463743 = 31463802
89 + 31463713 = 31463802
113 + 31463689 = 31463802
211 + 31463591 = 31463802
269 + 31463533 = 31463802

Showing the first eight; more decompositions exist.
