Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578730, here are decompositions:

23 + 33578707 = 33578730
37 + 33578693 = 33578730
43 + 33578687 = 33578730
47 + 33578683 = 33578730
71 + 33578659 = 33578730
79 + 33578651 = 33578730
89 + 33578641 = 33578730
113 + 33578617 = 33578730

Showing the first eight; more decompositions exist.
