Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719836, here are decompositions:

5 + 8719831 = 8719836
17 + 8719819 = 8719836
19 + 8719817 = 8719836
23 + 8719813 = 8719836
89 + 8719747 = 8719836
137 + 8719699 = 8719836
173 + 8719663 = 8719836
233 + 8719603 = 8719836

Showing the first eight; more decompositions exist.
