Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507472, here are decompositions:

29 + 33507443 = 33507472
59 + 33507413 = 33507472
71 + 33507401 = 33507472
113 + 33507359 = 33507472
443 + 33507029 = 33507472
569 + 33506903 = 33507472
653 + 33506819 = 33507472
809 + 33506663 = 33507472

Showing the first eight; more decompositions exist.
