Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578418, here are decompositions:

7 + 33578411 = 33578418
31 + 33578387 = 33578418
127 + 33578291 = 33578418
131 + 33578287 = 33578418
149 + 33578269 = 33578418
151 + 33578267 = 33578418
157 + 33578261 = 33578418
199 + 33578219 = 33578418

Showing the first eight; more decompositions exist.
