Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543648, here are decompositions:

7 + 33543641 = 33543648
71 + 33543577 = 33543648
101 + 33543547 = 33543648
109 + 33543539 = 33543648
137 + 33543511 = 33543648
139 + 33543509 = 33543648
167 + 33543481 = 33543648
227 + 33543421 = 33543648

Showing the first eight; more decompositions exist.
