Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727718, here are decompositions:

17 + 8727701 = 8727718
29 + 8727689 = 8727718
59 + 8727659 = 8727718
107 + 8727611 = 8727718
149 + 8727569 = 8727718
179 + 8727539 = 8727718
359 + 8727359 = 8727718
401 + 8727317 = 8727718

Showing the first eight; more decompositions exist.
