Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587860, here are decompositions:

3 + 33587857 = 33587860
29 + 33587831 = 33587860
71 + 33587789 = 33587860
191 + 33587669 = 33587860
227 + 33587633 = 33587860
311 + 33587549 = 33587860
347 + 33587513 = 33587860
353 + 33587507 = 33587860

Showing the first eight; more decompositions exist.
