Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578490, here are decompositions:

7 + 33578483 = 33578490
13 + 33578477 = 33578490
17 + 33578473 = 33578490
41 + 33578449 = 33578490
47 + 33578443 = 33578490
53 + 33578437 = 33578490
61 + 33578429 = 33578490
67 + 33578423 = 33578490

Showing the first eight; more decompositions exist.
