Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33474740, here are decompositions:

37 + 33474703 = 33474740
43 + 33474697 = 33474740
67 + 33474673 = 33474740
73 + 33474667 = 33474740
109 + 33474631 = 33474740
139 + 33474601 = 33474740
163 + 33474577 = 33474740
181 + 33474559 = 33474740

Showing the first eight; more decompositions exist.
