Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628132, here are decompositions:

11 + 8628121 = 8628132
83 + 8628049 = 8628132
101 + 8628031 = 8628132
113 + 8628019 = 8628132
179 + 8627953 = 8628132
193 + 8627939 = 8628132
223 + 8627909 = 8628132
229 + 8627903 = 8628132

Showing the first eight; more decompositions exist.
