Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538740, here are decompositions:

19 + 33538721 = 33538740
29 + 33538711 = 33538740
31 + 33538709 = 33538740
41 + 33538699 = 33538740
61 + 33538679 = 33538740
97 + 33538643 = 33538740
101 + 33538639 = 33538740
107 + 33538633 = 33538740

Showing the first eight; more decompositions exist.
