Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553840, here are decompositions:

3 + 33553837 = 33553840
41 + 33553799 = 33553840
53 + 33553787 = 33553840
71 + 33553769 = 33553840
101 + 33553739 = 33553840
113 + 33553727 = 33553840
179 + 33553661 = 33553840
191 + 33553649 = 33553840

Showing the first eight; more decompositions exist.
