Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718590, here are decompositions:

19 + 8718571 = 8718590
103 + 8718487 = 8718590
151 + 8718439 = 8718590
163 + 8718427 = 8718590
241 + 8718349 = 8718590
277 + 8718313 = 8718590
313 + 8718277 = 8718590
373 + 8718217 = 8718590

Showing the first eight; more decompositions exist.
