Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505578, here are decompositions:

5 + 33505573 = 33505578
11 + 33505567 = 33505578
31 + 33505547 = 33505578
59 + 33505519 = 33505578
79 + 33505499 = 33505578
131 + 33505447 = 33505578
137 + 33505441 = 33505578
241 + 33505337 = 33505578

Showing the first eight; more decompositions exist.
