Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577680, here are decompositions:

29 + 33577651 = 33577680
43 + 33577637 = 33577680
107 + 33577573 = 33577680
109 + 33577571 = 33577680
151 + 33577529 = 33577680
163 + 33577517 = 33577680
167 + 33577513 = 33577680
179 + 33577501 = 33577680

Showing the first eight; more decompositions exist.
