Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555428, here are decompositions:

7 + 33555421 = 33555428
31 + 33555397 = 33555428
37 + 33555391 = 33555428
139 + 33555289 = 33555428
157 + 33555271 = 33555428
211 + 33555217 = 33555428
229 + 33555199 = 33555428
349 + 33555079 = 33555428

Showing the first eight; more decompositions exist.
