Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690668, here are decompositions:

5 + 8690663 = 8690668
29 + 8690639 = 8690668
101 + 8690567 = 8690668
137 + 8690531 = 8690668
179 + 8690489 = 8690668
191 + 8690477 = 8690668
257 + 8690411 = 8690668
269 + 8690399 = 8690668

Showing the first eight; more decompositions exist.
