Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577840, here are decompositions:

11 + 33577829 = 33577840
17 + 33577823 = 33577840
59 + 33577781 = 33577840
113 + 33577727 = 33577840
269 + 33577571 = 33577840
293 + 33577547 = 33577840
311 + 33577529 = 33577840
383 + 33577457 = 33577840

Showing the first eight; more decompositions exist.
