Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491898, here are decompositions:

61 + 33491837 = 33491898
67 + 33491831 = 33491898
71 + 33491827 = 33491898
131 + 33491767 = 33491898
137 + 33491761 = 33491898
151 + 33491747 = 33491898
157 + 33491741 = 33491898
179 + 33491719 = 33491898

Showing the first eight; more decompositions exist.
