Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531186, here are decompositions:

19 + 33531167 = 33531186
89 + 33531097 = 33531186
103 + 33531083 = 33531186
109 + 33531077 = 33531186
127 + 33531059 = 33531186
137 + 33531049 = 33531186
167 + 33531019 = 33531186
349 + 33530837 = 33531186

Showing the first eight; more decompositions exist.
