Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531428, here are decompositions:

31 + 33531397 = 33531428
37 + 33531391 = 33531428
79 + 33531349 = 33531428
109 + 33531319 = 33531428
181 + 33531247 = 33531428
199 + 33531229 = 33531428
241 + 33531187 = 33531428
331 + 33531097 = 33531428

Showing the first eight; more decompositions exist.
