Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545240, here are decompositions:

13 + 33545227 = 33545240
67 + 33545173 = 33545240
73 + 33545167 = 33545240
139 + 33545101 = 33545240
241 + 33544999 = 33545240
373 + 33544867 = 33545240
397 + 33544843 = 33545240
457 + 33544783 = 33545240

Showing the first eight; more decompositions exist.
