Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658066, here are decompositions:

7 + 8658059 = 8658066
23 + 8658043 = 8658066
83 + 8657983 = 8658066
97 + 8657969 = 8658066
139 + 8657927 = 8658066
163 + 8657903 = 8658066
233 + 8657833 = 8658066
239 + 8657827 = 8658066

Showing the first eight; more decompositions exist.
