Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742016, here are decompositions:

5 + 8742011 = 8742016
29 + 8741987 = 8742016
83 + 8741933 = 8742016
149 + 8741867 = 8742016
263 + 8741753 = 8742016
317 + 8741699 = 8742016
557 + 8741459 = 8742016
653 + 8741363 = 8742016

Showing the first eight; more decompositions exist.
