Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33554778, here are decompositions:

7 + 33554771 = 33554778
17 + 33554761 = 33554778
41 + 33554737 = 33554778
79 + 33554699 = 33554778
137 + 33554641 = 33554778
139 + 33554639 = 33554778
197 + 33554581 = 33554778
199 + 33554579 = 33554778

Showing the first eight; more decompositions exist.
