Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587900, here are decompositions:

7 + 33587893 = 33587900
37 + 33587863 = 33587900
43 + 33587857 = 33587900
67 + 33587833 = 33587900
97 + 33587803 = 33587900
109 + 33587791 = 33587900
139 + 33587761 = 33587900
163 + 33587737 = 33587900

Showing the first eight; more decompositions exist.
