Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549990, here are decompositions:

7 + 33549983 = 33549990
13 + 33549977 = 33549990
17 + 33549973 = 33549990
29 + 33549961 = 33549990
83 + 33549907 = 33549990
101 + 33549889 = 33549990
127 + 33549863 = 33549990
157 + 33549833 = 33549990

Showing the first eight; more decompositions exist.
