Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545918, here are decompositions:

67 + 33545851 = 33545918
79 + 33545839 = 33545918
421 + 33545497 = 33545918
541 + 33545377 = 33545918
547 + 33545371 = 33545918
607 + 33545311 = 33545918
691 + 33545227 = 33545918
727 + 33545191 = 33545918

Showing the first eight; more decompositions exist.
