Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531288, here are decompositions:

5 + 33531283 = 33531288
19 + 33531269 = 33531288
41 + 33531247 = 33531288
59 + 33531229 = 33531288
101 + 33531187 = 33531288
191 + 33531097 = 33531288
211 + 33531077 = 33531288
227 + 33531061 = 33531288

Showing the first eight; more decompositions exist.
