Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507644, here are decompositions:

3 + 33507641 = 33507644
13 + 33507631 = 33507644
43 + 33507601 = 33507644
67 + 33507577 = 33507644
103 + 33507541 = 33507644
337 + 33507307 = 33507644
397 + 33507247 = 33507644
421 + 33507223 = 33507644

Showing the first eight; more decompositions exist.
