Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452304, here are decompositions:

3 + 31452301 = 31452304
71 + 31452233 = 31452304
101 + 31452203 = 31452304
131 + 31452173 = 31452304
167 + 31452137 = 31452304
173 + 31452131 = 31452304
263 + 31452041 = 31452304
311 + 31451993 = 31452304

Showing the first eight; more decompositions exist.
