Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557872, here are decompositions:

83 + 33557789 = 33557872
191 + 33557681 = 33557872
269 + 33557603 = 33557872
311 + 33557561 = 33557872
401 + 33557471 = 33557872
419 + 33557453 = 33557872
443 + 33557429 = 33557872
449 + 33557423 = 33557872

Showing the first eight; more decompositions exist.
