Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578748, here are decompositions:

41 + 33578707 = 33578748
61 + 33578687 = 33578748
89 + 33578659 = 33578748
97 + 33578651 = 33578748
107 + 33578641 = 33578748
131 + 33578617 = 33578748
149 + 33578599 = 33578748
179 + 33578569 = 33578748

Showing the first eight; more decompositions exist.
