Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463928, here are decompositions:

7 + 31463921 = 31463928
17 + 31463911 = 31463928
19 + 31463909 = 31463928
31 + 31463897 = 31463928
37 + 31463891 = 31463928
71 + 31463857 = 31463928
79 + 31463849 = 31463928
101 + 31463827 = 31463928

Showing the first eight; more decompositions exist.
