Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453364, here are decompositions:

3 + 31453361 = 31453364
31 + 31453333 = 31453364
43 + 31453321 = 31453364
97 + 31453267 = 31453364
157 + 31453207 = 31453364
193 + 31453171 = 31453364
223 + 31453141 = 31453364
421 + 31452943 = 31453364

Showing the first eight; more decompositions exist.
