Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587578, here are decompositions:

29 + 33587549 = 33587578
41 + 33587537 = 33587578
71 + 33587507 = 33587578
107 + 33587471 = 33587578
239 + 33587339 = 33587578
257 + 33587321 = 33587578
317 + 33587261 = 33587578
359 + 33587219 = 33587578

Showing the first eight; more decompositions exist.
