Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581824, here are decompositions:

5 + 33581819 = 33581824
11 + 33581813 = 33581824
83 + 33581741 = 33581824
131 + 33581693 = 33581824
137 + 33581687 = 33581824
251 + 33581573 = 33581824
383 + 33581441 = 33581824
431 + 33581393 = 33581824

Showing the first eight; more decompositions exist.
