Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453296, here are decompositions:

13 + 31453283 = 31453296
29 + 31453267 = 31453296
47 + 31453249 = 31453296
89 + 31453207 = 31453296
103 + 31453193 = 31453296
137 + 31453159 = 31453296
139 + 31453157 = 31453296
163 + 31453133 = 31453296

Showing the first eight; more decompositions exist.
