Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719530, here are decompositions:

11 + 8719519 = 8719530
47 + 8719483 = 8719530
89 + 8719441 = 8719530
109 + 8719421 = 8719530
139 + 8719391 = 8719530
151 + 8719379 = 8719530
163 + 8719367 = 8719530
181 + 8719349 = 8719530

Showing the first eight; more decompositions exist.
