Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587928, here are decompositions:

7 + 33587921 = 33587928
61 + 33587867 = 33587928
71 + 33587857 = 33587928
97 + 33587831 = 33587928
137 + 33587791 = 33587928
139 + 33587789 = 33587928
167 + 33587761 = 33587928
191 + 33587737 = 33587928

Showing the first eight; more decompositions exist.
