Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600868, here are decompositions:

61 + 8600807 = 8600868
79 + 8600789 = 8600868
127 + 8600741 = 8600868
149 + 8600719 = 8600868
151 + 8600717 = 8600868
167 + 8600701 = 8600868
191 + 8600677 = 8600868
229 + 8600639 = 8600868

Showing the first eight; more decompositions exist.
