Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578636, here are decompositions:

19 + 33578617 = 33578636
37 + 33578599 = 33578636
67 + 33578569 = 33578636
79 + 33578557 = 33578636
103 + 33578533 = 33578636
127 + 33578509 = 33578636
139 + 33578497 = 33578636
163 + 33578473 = 33578636

Showing the first eight; more decompositions exist.
