Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658012, here are decompositions:

29 + 8657983 = 8658012
43 + 8657969 = 8658012
79 + 8657933 = 8658012
89 + 8657923 = 8658012
109 + 8657903 = 8658012
131 + 8657881 = 8658012
163 + 8657849 = 8658012
179 + 8657833 = 8658012

Showing the first eight; more decompositions exist.
