Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489140, here are decompositions:

31 + 33489109 = 33489140
37 + 33489103 = 33489140
43 + 33489097 = 33489140
67 + 33489073 = 33489140
127 + 33489013 = 33489140
163 + 33488977 = 33489140
193 + 33488947 = 33489140
271 + 33488869 = 33489140

Showing the first eight; more decompositions exist.
