Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463964, here are decompositions:

5 + 31463959 = 31463964
23 + 31463941 = 31463964
43 + 31463921 = 31463964
53 + 31463911 = 31463964
67 + 31463897 = 31463964
71 + 31463893 = 31463964
73 + 31463891 = 31463964
107 + 31463857 = 31463964

Showing the first eight; more decompositions exist.
