Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538540, here are decompositions:

17 + 33538523 = 33538540
23 + 33538517 = 33538540
29 + 33538511 = 33538540
41 + 33538499 = 33538540
59 + 33538481 = 33538540
71 + 33538469 = 33538540
83 + 33538457 = 33538540
137 + 33538403 = 33538540

Showing the first eight; more decompositions exist.
