Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557490, here are decompositions:

19 + 33557471 = 33557490
23 + 33557467 = 33557490
37 + 33557453 = 33557490
61 + 33557429 = 33557490
67 + 33557423 = 33557490
73 + 33557417 = 33557490
79 + 33557411 = 33557490
103 + 33557387 = 33557490

Showing the first eight; more decompositions exist.
