Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491780, here are decompositions:

13 + 33491767 = 33491780
19 + 33491761 = 33491780
61 + 33491719 = 33491780
67 + 33491713 = 33491780
109 + 33491671 = 33491780
139 + 33491641 = 33491780
181 + 33491599 = 33491780
211 + 33491569 = 33491780

Showing the first eight; more decompositions exist.
