Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628278, here are decompositions:

7 + 8628271 = 8628278
97 + 8628181 = 8628278
157 + 8628121 = 8628278
181 + 8628097 = 8628278
229 + 8628049 = 8628278
271 + 8628007 = 8628278
331 + 8627947 = 8628278
367 + 8627911 = 8628278

Showing the first eight; more decompositions exist.
