Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587720, here are decompositions:

13 + 33587707 = 33587720
37 + 33587683 = 33587720
43 + 33587677 = 33587720
73 + 33587647 = 33587720
139 + 33587581 = 33587720
163 + 33587557 = 33587720
211 + 33587509 = 33587720
241 + 33587479 = 33587720

Showing the first eight; more decompositions exist.
