Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578144, here are decompositions:

13 + 33578131 = 33578144
37 + 33578107 = 33578144
211 + 33577933 = 33578144
571 + 33577573 = 33578144
631 + 33577513 = 33578144
643 + 33577501 = 33578144
823 + 33577321 = 33578144
937 + 33577207 = 33578144

Showing the first eight; more decompositions exist.
