Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463880, here are decompositions:

23 + 31463857 = 31463880
31 + 31463849 = 31463880
37 + 31463843 = 31463880
53 + 31463827 = 31463880
73 + 31463807 = 31463880
83 + 31463797 = 31463880
101 + 31463779 = 31463880
113 + 31463767 = 31463880

Showing the first eight; more decompositions exist.
