Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578220, here are decompositions:

23 + 33578197 = 33578220
29 + 33578191 = 33578220
73 + 33578147 = 33578220
89 + 33578131 = 33578220
101 + 33578119 = 33578220
113 + 33578107 = 33578220
241 + 33577979 = 33578220
281 + 33577939 = 33578220

Showing the first eight; more decompositions exist.
