Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33536778, here are decompositions:

19 + 33536759 = 33536778
61 + 33536717 = 33536778
71 + 33536707 = 33536778
101 + 33536677 = 33536778
139 + 33536639 = 33536778
151 + 33536627 = 33536778
199 + 33536579 = 33536778
211 + 33536567 = 33536778

Showing the first eight; more decompositions exist.
