Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33573840, here are decompositions:

7 + 33573833 = 33573840
11 + 33573829 = 33573840
17 + 33573823 = 33573840
19 + 33573821 = 33573840
29 + 33573811 = 33573840
31 + 33573809 = 33573840
43 + 33573797 = 33573840
59 + 33573781 = 33573840

Showing the first eight; more decompositions exist.
