Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719998, here are decompositions:

11 + 8719987 = 8719998
37 + 8719961 = 8719998
47 + 8719951 = 8719998
59 + 8719939 = 8719998
151 + 8719847 = 8719998
167 + 8719831 = 8719998
179 + 8719819 = 8719998
181 + 8719817 = 8719998

Showing the first eight; more decompositions exist.
