Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581872, here are decompositions:

3 + 33581869 = 33581872
11 + 33581861 = 33581872
53 + 33581819 = 33581872
59 + 33581813 = 33581872
131 + 33581741 = 33581872
179 + 33581693 = 33581872
251 + 33581621 = 33581872
431 + 33581441 = 33581872

Showing the first eight; more decompositions exist.
