Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531242, here are decompositions:

13 + 33531229 = 33531242
181 + 33531061 = 33531242
193 + 33531049 = 33531242
211 + 33531031 = 33531242
223 + 33531019 = 33531242
271 + 33530971 = 33531242
541 + 33530701 = 33531242
673 + 33530569 = 33531242

Showing the first eight; more decompositions exist.
