Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545666, here are decompositions:

43 + 33545623 = 33545666
67 + 33545599 = 33545666
109 + 33545557 = 33545666
139 + 33545527 = 33545666
223 + 33545443 = 33545666
277 + 33545389 = 33545666
283 + 33545383 = 33545666
337 + 33545329 = 33545666

Showing the first eight; more decompositions exist.
