Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636988, here are decompositions:

29 + 8636959 = 8636988
67 + 8636921 = 8636988
71 + 8636917 = 8636988
79 + 8636909 = 8636988
89 + 8636899 = 8636988
131 + 8636857 = 8636988
149 + 8636839 = 8636988
197 + 8636791 = 8636988

Showing the first eight; more decompositions exist.
