Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538644, here are decompositions:

5 + 33538639 = 33538644
11 + 33538633 = 33538644
17 + 33538627 = 33538644
43 + 33538601 = 33538644
101 + 33538543 = 33538644
127 + 33538517 = 33538644
137 + 33538507 = 33538644
163 + 33538481 = 33538644

Showing the first eight; more decompositions exist.
