Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578420, here are decompositions:

67 + 33578353 = 33578420
151 + 33578269 = 33578420
223 + 33578197 = 33578420
229 + 33578191 = 33578420
313 + 33578107 = 33578420
409 + 33578011 = 33578420
487 + 33577933 = 33578420
769 + 33577651 = 33578420

Showing the first eight; more decompositions exist.
