Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453204, here are decompositions:

11 + 31453193 = 31453204
23 + 31453181 = 31453204
47 + 31453157 = 31453204
71 + 31453133 = 31453204
227 + 31452977 = 31453204
353 + 31452851 = 31453204
401 + 31452803 = 31453204
521 + 31452683 = 31453204

Showing the first eight; more decompositions exist.
