Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463868, here are decompositions:

11 + 31463857 = 31463868
19 + 31463849 = 31463868
41 + 31463827 = 31463868
61 + 31463807 = 31463868
71 + 31463797 = 31463868
89 + 31463779 = 31463868
101 + 31463767 = 31463868
109 + 31463759 = 31463868

Showing the first eight; more decompositions exist.
