Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463886, here are decompositions:

7 + 31463879 = 31463886
29 + 31463857 = 31463886
37 + 31463849 = 31463886
43 + 31463843 = 31463886
59 + 31463827 = 31463886
79 + 31463807 = 31463886
89 + 31463797 = 31463886
107 + 31463779 = 31463886

Showing the first eight; more decompositions exist.
