Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491820, here are decompositions:

17 + 33491803 = 33491820
41 + 33491779 = 33491820
53 + 33491767 = 33491820
59 + 33491761 = 33491820
73 + 33491747 = 33491820
79 + 33491741 = 33491820
101 + 33491719 = 33491820
107 + 33491713 = 33491820

Showing the first eight; more decompositions exist.
