Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547680, here are decompositions:

53 + 33547627 = 33547680
73 + 33547607 = 33547680
97 + 33547583 = 33547680
137 + 33547543 = 33547680
151 + 33547529 = 33547680
163 + 33547517 = 33547680
167 + 33547513 = 33547680
191 + 33547489 = 33547680

Showing the first eight; more decompositions exist.
