Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533428, here are decompositions:

19 + 31533409 = 31533428
331 + 31533097 = 31533428
337 + 31533091 = 31533428
457 + 31532971 = 31533428
547 + 31532881 = 31533428
691 + 31532737 = 31533428
769 + 31532659 = 31533428
877 + 31532551 = 31533428

Showing the first eight; more decompositions exist.
