Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555400, here are decompositions:

3 + 33555397 = 33555400
17 + 33555383 = 33555400
23 + 33555377 = 33555400
59 + 33555341 = 33555400
83 + 33555317 = 33555400
107 + 33555293 = 33555400
113 + 33555287 = 33555400
149 + 33555251 = 33555400

Showing the first eight; more decompositions exist.
