Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555678, here are decompositions:

11 + 33555667 = 33555678
17 + 33555661 = 33555678
19 + 33555659 = 33555678
31 + 33555647 = 33555678
61 + 33555617 = 33555678
67 + 33555611 = 33555678
151 + 33555527 = 33555678
179 + 33555499 = 33555678

Showing the first eight; more decompositions exist.
