Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533476, here are decompositions:

67 + 31533409 = 31533476
97 + 31533379 = 31533476
349 + 31533127 = 31533476
379 + 31533097 = 31533476
463 + 31533013 = 31533476
577 + 31532899 = 31533476
613 + 31532863 = 31533476
643 + 31532833 = 31533476

Showing the first eight; more decompositions exist.
