Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506778, here are decompositions:

5 + 33506773 = 33506778
37 + 33506741 = 33506778
89 + 33506689 = 33506778
181 + 33506597 = 33506778
191 + 33506587 = 33506778
197 + 33506581 = 33506778
199 + 33506579 = 33506778
229 + 33506549 = 33506778

Showing the first eight; more decompositions exist.
