Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531512, here are decompositions:

13 + 33531499 = 33531512
43 + 33531469 = 33531512
61 + 33531451 = 33531512
73 + 33531439 = 33531512
109 + 33531403 = 33531512
163 + 33531349 = 33531512
193 + 33531319 = 33531512
229 + 33531283 = 33531512

Showing the first eight; more decompositions exist.
