Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538784, here are decompositions:

43 + 33538741 = 33538784
73 + 33538711 = 33538784
151 + 33538633 = 33538784
157 + 33538627 = 33538784
241 + 33538543 = 33538784
277 + 33538507 = 33538784
337 + 33538447 = 33538784
397 + 33538387 = 33538784

Showing the first eight; more decompositions exist.
