Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533896, here are decompositions:

67 + 31533829 = 31533896
73 + 31533823 = 31533896
127 + 31533769 = 31533896
283 + 31533613 = 31533896
349 + 31533547 = 31533896
379 + 31533517 = 31533896
397 + 31533499 = 31533896
487 + 31533409 = 31533896

Showing the first eight; more decompositions exist.
