Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543578, here are decompositions:

31 + 33543547 = 33543578
67 + 33543511 = 33543578
97 + 33543481 = 33543578
139 + 33543439 = 33543578
157 + 33543421 = 33543578
241 + 33543337 = 33543578
379 + 33543199 = 33543578
421 + 33543157 = 33543578

Showing the first eight; more decompositions exist.
