Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531318, here are decompositions:

19 + 33531299 = 33531318
71 + 33531247 = 33531318
89 + 33531229 = 33531318
131 + 33531187 = 33531318
151 + 33531167 = 33531318
241 + 33531077 = 33531318
257 + 33531061 = 33531318
269 + 33531049 = 33531318

Showing the first eight; more decompositions exist.
