Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707836, here are decompositions:

19 + 8707817 = 8707836
43 + 8707793 = 8707836
73 + 8707763 = 8707836
83 + 8707753 = 8707836
89 + 8707747 = 8707836
139 + 8707697 = 8707836
149 + 8707687 = 8707836
167 + 8707669 = 8707836

Showing the first eight; more decompositions exist.
