Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719028, here are decompositions:

7 + 8719021 = 8719028
79 + 8718949 = 8719028
151 + 8718877 = 8719028
229 + 8718799 = 8719028
271 + 8718757 = 8719028
379 + 8718649 = 8719028
457 + 8718571 = 8719028
541 + 8718487 = 8719028

Showing the first eight; more decompositions exist.
