Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453896, here are decompositions:

13 + 31453883 = 31453896
17 + 31453879 = 31453896
29 + 31453867 = 31453896
73 + 31453823 = 31453896
83 + 31453813 = 31453896
113 + 31453783 = 31453896
163 + 31453733 = 31453896
197 + 31453699 = 31453896

Showing the first eight; more decompositions exist.
