Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556578, here are decompositions:

7 + 33556571 = 33556578
19 + 33556559 = 33556578
31 + 33556547 = 33556578
47 + 33556531 = 33556578
71 + 33556507 = 33556578
79 + 33556499 = 33556578
149 + 33556429 = 33556578
179 + 33556399 = 33556578

Showing the first eight; more decompositions exist.
