Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518778, here are decompositions:

11 + 33518767 = 33518778
47 + 33518731 = 33518778
101 + 33518677 = 33518778
109 + 33518669 = 33518778
127 + 33518651 = 33518778
157 + 33518621 = 33518778
191 + 33518587 = 33518778
239 + 33518539 = 33518778

Showing the first eight; more decompositions exist.
