Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719986, here are decompositions:

43 + 8719943 = 8719986
47 + 8719939 = 8719986
83 + 8719903 = 8719986
113 + 8719873 = 8719986
139 + 8719847 = 8719986
167 + 8719819 = 8719986
173 + 8719813 = 8719986
239 + 8719747 = 8719986

Showing the first eight; more decompositions exist.
