Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497730, here are decompositions:

43 + 33497687 = 33497730
59 + 33497671 = 33497730
73 + 33497657 = 33497730
107 + 33497623 = 33497730
127 + 33497603 = 33497730
137 + 33497593 = 33497730
151 + 33497579 = 33497730
163 + 33497567 = 33497730

Showing the first eight; more decompositions exist.
