Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531248, here are decompositions:

19 + 33531229 = 33531248
61 + 33531187 = 33531248
151 + 33531097 = 33531248
199 + 33531049 = 33531248
229 + 33531019 = 33531248
271 + 33530977 = 33531248
277 + 33530971 = 33531248
349 + 33530899 = 33531248

Showing the first eight; more decompositions exist.
