Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578040, here are decompositions:

29 + 33578011 = 33578040
37 + 33578003 = 33578040
61 + 33577979 = 33578040
73 + 33577967 = 33578040
101 + 33577939 = 33578040
103 + 33577937 = 33578040
107 + 33577933 = 33578040
113 + 33577927 = 33578040

Showing the first eight; more decompositions exist.
