Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555520, here are decompositions:

3 + 33555517 = 33555520
23 + 33555497 = 33555520
59 + 33555461 = 33555520
71 + 33555449 = 33555520
101 + 33555419 = 33555520
137 + 33555383 = 33555520
179 + 33555341 = 33555520
227 + 33555293 = 33555520

Showing the first eight; more decompositions exist.
