Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717190, here are decompositions:

19 + 8717171 = 8717190
59 + 8717131 = 8717190
67 + 8717123 = 8717190
71 + 8717119 = 8717190
73 + 8717117 = 8717190
149 + 8717041 = 8717190
179 + 8717011 = 8717190
191 + 8716999 = 8717190

Showing the first eight; more decompositions exist.
