Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453926, here are decompositions:

17 + 31453909 = 31453926
29 + 31453897 = 31453926
43 + 31453883 = 31453926
47 + 31453879 = 31453926
59 + 31453867 = 31453926
103 + 31453823 = 31453926
113 + 31453813 = 31453926
193 + 31453733 = 31453926

Showing the first eight; more decompositions exist.
