Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722016, here are decompositions:

7 + 8722009 = 8722016
19 + 8721997 = 8722016
103 + 8721913 = 8722016
109 + 8721907 = 8722016
139 + 8721877 = 8722016
349 + 8721667 = 8722016
409 + 8721607 = 8722016
547 + 8721469 = 8722016

Showing the first eight; more decompositions exist.
