Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578818, here are decompositions:

11 + 33578807 = 33578818
71 + 33578747 = 33578818
131 + 33578687 = 33578818
167 + 33578651 = 33578818
311 + 33578507 = 33578818
389 + 33578429 = 33578818
431 + 33578387 = 33578818
557 + 33578261 = 33578818

Showing the first eight; more decompositions exist.
