Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531000, here are decompositions:

23 + 33530977 = 33531000
29 + 33530971 = 33531000
31 + 33530969 = 33531000
101 + 33530899 = 33531000
163 + 33530837 = 33531000
211 + 33530789 = 33531000
227 + 33530773 = 33531000
241 + 33530759 = 33531000

Showing the first eight; more decompositions exist.
