Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515730, here are decompositions:

11 + 33515719 = 33515730
19 + 33515711 = 33515730
23 + 33515707 = 33515730
29 + 33515701 = 33515730
37 + 33515693 = 33515730
97 + 33515633 = 33515730
113 + 33515617 = 33515730
137 + 33515593 = 33515730

Showing the first eight; more decompositions exist.
