Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521136, here are decompositions:

37 + 33521099 = 33521136
53 + 33521083 = 33521136
79 + 33521057 = 33521136
97 + 33521039 = 33521136
127 + 33521009 = 33521136
149 + 33520987 = 33521136
157 + 33520979 = 33521136
163 + 33520973 = 33521136

Showing the first eight; more decompositions exist.
