Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556878, here are decompositions:

11 + 33556867 = 33556878
31 + 33556847 = 33556878
37 + 33556841 = 33556878
41 + 33556837 = 33556878
67 + 33556811 = 33556878
109 + 33556769 = 33556878
167 + 33556711 = 33556878
197 + 33556681 = 33556878

Showing the first eight; more decompositions exist.
