Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587918, here are decompositions:

61 + 33587857 = 33587918
109 + 33587809 = 33587918
127 + 33587791 = 33587918
157 + 33587761 = 33587918
181 + 33587737 = 33587918
211 + 33587707 = 33587918
241 + 33587677 = 33587918
271 + 33587647 = 33587918

Showing the first eight; more decompositions exist.
