Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557730, here are decompositions:

23 + 33557707 = 33557730
29 + 33557701 = 33557730
47 + 33557683 = 33557730
67 + 33557663 = 33557730
103 + 33557627 = 33557730
113 + 33557617 = 33557730
127 + 33557603 = 33557730
163 + 33557567 = 33557730

Showing the first eight; more decompositions exist.
