Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485730, here are decompositions:

13 + 33485717 = 33485730
17 + 33485713 = 33485730
29 + 33485701 = 33485730
41 + 33485689 = 33485730
43 + 33485687 = 33485730
67 + 33485663 = 33485730
137 + 33485593 = 33485730
163 + 33485567 = 33485730

Showing the first eight; more decompositions exist.
