Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555740, here are decompositions:

3 + 33555737 = 33555740
13 + 33555727 = 33555740
37 + 33555703 = 33555740
61 + 33555679 = 33555740
73 + 33555667 = 33555740
79 + 33555661 = 33555740
157 + 33555583 = 33555740
223 + 33555517 = 33555740

Showing the first eight; more decompositions exist.
