Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533506, here are decompositions:

7 + 31533499 = 31533506
97 + 31533409 = 31533506
127 + 31533379 = 31533506
163 + 31533343 = 31533506
373 + 31533133 = 31533506
379 + 31533127 = 31533506
409 + 31533097 = 31533506
547 + 31532959 = 31533506

Showing the first eight; more decompositions exist.
