Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453384, here are decompositions:

23 + 31453361 = 31453384
101 + 31453283 = 31453384
191 + 31453193 = 31453384
227 + 31453157 = 31453384
251 + 31453133 = 31453384
653 + 31452731 = 31453384
701 + 31452683 = 31453384
761 + 31452623 = 31453384

Showing the first eight; more decompositions exist.
