Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538128, here are decompositions:

37 + 33538091 = 33538128
47 + 33538081 = 33538128
59 + 33538069 = 33538128
79 + 33538049 = 33538128
101 + 33538027 = 33538128
157 + 33537971 = 33538128
167 + 33537961 = 33538128
229 + 33537899 = 33538128

Showing the first eight; more decompositions exist.
