Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591180, here are decompositions:

19 + 33591161 = 33591180
41 + 33591139 = 33591180
79 + 33591101 = 33591180
83 + 33591097 = 33591180
97 + 33591083 = 33591180
113 + 33591067 = 33591180
131 + 33591049 = 33591180
193 + 33590987 = 33591180

Showing the first eight; more decompositions exist.
