Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533040, here are decompositions:

7 + 33533033 = 33533040
11 + 33533029 = 33533040
19 + 33533021 = 33533040
67 + 33532973 = 33533040
71 + 33532969 = 33533040
89 + 33532951 = 33533040
97 + 33532943 = 33533040
109 + 33532931 = 33533040

Showing the first eight; more decompositions exist.
