Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453254, here are decompositions:

5 + 31453249 = 31453254
13 + 31453241 = 31453254
47 + 31453207 = 31453254
61 + 31453193 = 31453254
73 + 31453181 = 31453254
83 + 31453171 = 31453254
97 + 31453157 = 31453254
113 + 31453141 = 31453254

Showing the first eight; more decompositions exist.
