Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453368, here are decompositions:

7 + 31453361 = 31453368
47 + 31453321 = 31453368
101 + 31453267 = 31453368
127 + 31453241 = 31453368
197 + 31453171 = 31453368
211 + 31453157 = 31453368
227 + 31453141 = 31453368
347 + 31453021 = 31453368

Showing the first eight; more decompositions exist.
