Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690886, here are decompositions:

19 + 8690867 = 8690886
59 + 8690827 = 8690886
73 + 8690813 = 8690886
89 + 8690797 = 8690886
97 + 8690789 = 8690886
103 + 8690783 = 8690886
173 + 8690713 = 8690886
223 + 8690663 = 8690886

Showing the first eight; more decompositions exist.
