Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587980, here are decompositions:

11 + 33587969 = 33587980
59 + 33587921 = 33587980
113 + 33587867 = 33587980
149 + 33587831 = 33587980
191 + 33587789 = 33587980
311 + 33587669 = 33587980
347 + 33587633 = 33587980
431 + 33587549 = 33587980

Showing the first eight; more decompositions exist.
