Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557550, here are decompositions:

7 + 33557543 = 33557550
29 + 33557521 = 33557550
41 + 33557509 = 33557550
79 + 33557471 = 33557550
83 + 33557467 = 33557550
97 + 33557453 = 33557550
127 + 33557423 = 33557550
137 + 33557413 = 33557550

Showing the first eight; more decompositions exist.
