Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517856, here are decompositions:

7 + 33517849 = 33517856
103 + 33517753 = 33517856
109 + 33517747 = 33517856
223 + 33517633 = 33517856
283 + 33517573 = 33517856
499 + 33517357 = 33517856
739 + 33517117 = 33517856
769 + 33517087 = 33517856

Showing the first eight; more decompositions exist.
