Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491800, here are decompositions:

53 + 33491747 = 33491800
59 + 33491741 = 33491800
71 + 33491729 = 33491800
107 + 33491693 = 33491800
179 + 33491621 = 33491800
197 + 33491603 = 33491800
233 + 33491567 = 33491800
239 + 33491561 = 33491800

Showing the first eight; more decompositions exist.
