Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511200, here are decompositions:

29 + 33511171 = 33511200
43 + 33511157 = 33511200
61 + 33511139 = 33511200
67 + 33511133 = 33511200
71 + 33511129 = 33511200
101 + 33511099 = 33511200
109 + 33511091 = 33511200
113 + 33511087 = 33511200

Showing the first eight; more decompositions exist.
