Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491778, here are decompositions:

11 + 33491767 = 33491778
17 + 33491761 = 33491778
31 + 33491747 = 33491778
37 + 33491741 = 33491778
59 + 33491719 = 33491778
97 + 33491681 = 33491778
107 + 33491671 = 33491778
137 + 33491641 = 33491778

Showing the first eight; more decompositions exist.
