Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543618, here are decompositions:

41 + 33543577 = 33543618
71 + 33543547 = 33543618
79 + 33543539 = 33543618
89 + 33543529 = 33543618
107 + 33543511 = 33543618
109 + 33543509 = 33543618
131 + 33543487 = 33543618
137 + 33543481 = 33543618

Showing the first eight; more decompositions exist.
