Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531156, here are decompositions:

59 + 33531097 = 33531156
73 + 33531083 = 33531156
79 + 33531077 = 33531156
97 + 33531059 = 33531156
107 + 33531049 = 33531156
137 + 33531019 = 33531156
157 + 33530999 = 33531156
179 + 33530977 = 33531156

Showing the first eight; more decompositions exist.
