Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531728, here are decompositions:

67 + 33531661 = 33531728
151 + 33531577 = 33531728
229 + 33531499 = 33531728
277 + 33531451 = 33531728
331 + 33531397 = 33531728
337 + 33531391 = 33531728
379 + 33531349 = 33531728
409 + 33531319 = 33531728

Showing the first eight; more decompositions exist.
