Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587728, here are decompositions:

59 + 33587669 = 33587728
179 + 33587549 = 33587728
191 + 33587537 = 33587728
257 + 33587471 = 33587728
311 + 33587417 = 33587728
389 + 33587339 = 33587728
467 + 33587261 = 33587728
491 + 33587237 = 33587728

Showing the first eight; more decompositions exist.
