Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628260, here are decompositions:

73 + 8628187 = 8628260
79 + 8628181 = 8628260
103 + 8628157 = 8628260
139 + 8628121 = 8628260
163 + 8628097 = 8628260
211 + 8628049 = 8628260
229 + 8628031 = 8628260
241 + 8628019 = 8628260

Showing the first eight; more decompositions exist.
