Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718850, here are decompositions:

11 + 8718839 = 8718850
17 + 8718833 = 8718850
47 + 8718803 = 8718850
53 + 8718797 = 8718850
71 + 8718779 = 8718850
113 + 8718737 = 8718850
269 + 8718581 = 8718850
311 + 8718539 = 8718850

Showing the first eight; more decompositions exist.
