Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533512, here are decompositions:

13 + 31533499 = 31533512
61 + 31533451 = 31533512
103 + 31533409 = 31533512
379 + 31533133 = 31533512
421 + 31533091 = 31533512
499 + 31533013 = 31533512
541 + 31532971 = 31533512
613 + 31532899 = 31533512

Showing the first eight; more decompositions exist.
