Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33600990, here are decompositions:

11 + 33600979 = 33600990
13 + 33600977 = 33600990
61 + 33600929 = 33600990
97 + 33600893 = 33600990
107 + 33600883 = 33600990
109 + 33600881 = 33600990
113 + 33600877 = 33600990
131 + 33600859 = 33600990

Showing the first eight; more decompositions exist.
