Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538820, here are decompositions:

19 + 33538801 = 33538820
37 + 33538783 = 33538820
61 + 33538759 = 33538820
79 + 33538741 = 33538820
109 + 33538711 = 33538820
157 + 33538663 = 33538820
181 + 33538639 = 33538820
193 + 33538627 = 33538820

Showing the first eight; more decompositions exist.
