Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530872, here are decompositions:

59 + 33530813 = 33530872
83 + 33530789 = 33530872
113 + 33530759 = 33530872
131 + 33530741 = 33530872
503 + 33530369 = 33530872
563 + 33530309 = 33530872
569 + 33530303 = 33530872
593 + 33530279 = 33530872

Showing the first eight; more decompositions exist.
