Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557658, here are decompositions:

31 + 33557627 = 33557658
41 + 33557617 = 33557658
61 + 33557597 = 33557658
97 + 33557561 = 33557658
137 + 33557521 = 33557658
149 + 33557509 = 33557658
191 + 33557467 = 33557658
229 + 33557429 = 33557658

Showing the first eight; more decompositions exist.
