Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587680, here are decompositions:

3 + 33587677 = 33587680
11 + 33587669 = 33587680
47 + 33587633 = 33587680
131 + 33587549 = 33587680
167 + 33587513 = 33587680
173 + 33587507 = 33587680
263 + 33587417 = 33587680
317 + 33587363 = 33587680

Showing the first eight; more decompositions exist.
